CD74HC4316ME4 Equivalent & Substitute Parts

Part Overview

The CD74HC4316ME4 is a 4-circuit IC switch with SPST-NO configuration, manufactured by Texas Instruments in 16-SOIC surface mount packaging. This component functions as a single-pole single-throw normally-open switch array with 170Ohm on-state resistance, designed for analog signal switching and multiplexing applications across 2V to 6V single supply or ±1V to 5V dual supply operation.

The CD74HC4316ME4 is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for production and repair applications. Substitute parts must maintain electrical compatibility across switching characteristics, supply voltage ranges, and thermal operating conditions while accommodating packaging and compliance variations.

Substitute Part Grouping Explanation

Substitution of the CD74HC4316ME4 is determined by the following critical parameters:

Electrical Compatibility Criteria:

Switch circuit type (SPST-NO configuration)
Number of circuits (4-circuit array)
Multiplexer/demultiplexer ratio (1:1)
On-state resistance range (170Ohm nominal, with tolerance consideration)
Supply voltage compatibility (2V ~ 6V single supply minimum)
Operating temperature range (-55°C ~ 125°C minimum)

Mechanical Compatibility Criteria:

Package type (16-SOIC surface mount)

Engineering Selection Recommendations

Primary Substitute - CD74HC4316M96 (Texas Instruments)

CD74HC4316M96 is the recommended primary substitute. It maintains identical electrical specifications to the CD74HC4316ME4 across all critical parameters: 170Ohm on-state resistance, 5Ohm channel matching, 37ns switching time, and 200MHz bandwidth. The part is currently active in production status, ensuring long-term availability. It carries ROHS3 compliance and MSL 1 rating identical to the main part. Packaging is supplied in Tape & Reel format, standard for production environments.

Secondary Substitute - 74HC4316D,653 (Nexperia USA Inc.)

74HC4316D,653 provides functional equivalence with notable parameter variations. On-state resistance is 135Ohm (lower than the 170Ohm specification), offering improved performance in switching applications. Switch timing is significantly faster at 16ns versus 37ns, and channel capacitance is reduced to 4.6pF. Supply voltage range extends to 10V single supply, providing broader operational flexibility. The part is active in production with ROHS3 compliance. Operating temperature minimum is -40°C, which is 15°C higher than the main part specification. This part is suitable for applications where lower on-state resistance and faster switching are beneficial and the -40°C minimum temperature is acceptable.

Tertiary Substitute - MC74HC4316ADR2G (onsemi)

MC74HC4316ADR2G offers functional equivalence with performance improvements and configuration differences. On-state resistance is 90Ohm (significantly lower), with faster switching characteristics. The part features SPST-NO/NC configuration, providing both normally-open and normally-closed switch options. Channel-to-channel matching is 15Ohm, which is wider than the 5Ohm specification. Dual supply range extends to ±2V ~ 6V. The part is active in production with ROHS3 compliance and includes crosstalk specification of -80dB @ 1MHz. This part is suitable for applications requiring lower on-state resistance and dual-supply flexibility.

Not Recommended - CD74HC4316M (Harris Corporation)

CD74HC4316M is obsolete and carries RoHS non-compliant status, making it unsuitable for new designs or applications requiring regulatory compliance. While electrical specifications match the main part, the compliance status and obsolete status preclude its use in modern production environments.

Not Recommended - NLV74HC4316ADR2G (onsemi)

NLV74HC4316ADR2G is obsolete and carries automotive qualification (AEC-Q100). While it maintains the 1:1 multiplexer configuration and 4-circuit array, several critical parameters are not specified in the provided data. The obsolete status and automotive-specific qualification make it unsuitable as a general substitute.

Frequently Asked Questions (FAQ)

Q: Can CD74HC4316M96 be used as a direct replacement for CD74HC4316ME4?

A: Yes. CD74HC4316M96 maintains identical electrical specifications across all critical parameters: 170Ohm on-state resistance, 5Ohm channel matching, 37ns switching time, 200MHz bandwidth, and identical supply voltage ranges. Both parts use 16-SOIC packaging with identical pin configuration. The primary difference is packaging format (Tape & Reel versus unspecified) and product status (Active versus Obsolete). CD74HC4316M96 is the recommended direct replacement.

Q: What are the key differences between 74HC4316D,653 and the CD74HC4316ME4?

A: 74HC4316D,653 has lower on-state resistance (135Ohm versus 170Ohm), faster switching time (16ns versus 37ns), and reduced channel capacitance (4.6pF versus 5pF). It supports higher single supply voltage (up to 10V versus 6V). The operating temperature minimum is -40°C instead of -55°C. These differences make 74HC4316D,653 suitable for applications where lower resistance and faster switching are advantageous, provided the -40°C minimum temperature is acceptable.

Q: Is MC74HC4316ADR2G compatible with designs using CD74HC4316ME4?

A: MC74HC4316ADR2G is functionally compatible but with performance differences. It provides 90Ohm on-state resistance (lower than 170Ohm), improving switching performance. However, channel-to-channel matching is 15Ohm (wider than 5Ohm), which may affect applications requiring tight matching. The part also offers SPST-NO/NC configuration, providing additional switching flexibility. Designs must verify that the lower on-state resistance and wider matching tolerance are acceptable for the application.

Q: Why is CD74HC4316M not recommended as a substitute?

A: CD74HC4316M is classified as obsolete and carries RoHS non-compliant status. While electrical specifications match the main part, the RoHS non-compliance status makes it unsuitable for applications requiring regulatory compliance with modern environmental standards. The obsolete status also indicates limited future availability.

Q: What packaging formats are available for substitute parts?

A: CD74HC4316M96, MC74HC4316ADR2G, and 74HC4316D,653 are supplied in Tape & Reel (TR) format, standard for production and automated assembly. CD74HC4316M is supplied in Tube format. All parts use identical 16-SOIC surface mount packaging with 0.154" width (3.90mm), ensuring footprint compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: All recommended substitute parts (CD74HC4316M96, MC74HC4316ADR2G, and 74HC4316D,653) are ROHS3 compliant. CD74HC4316M is RoHS non-compliant and is not recommended. NLV74HC4316ADR2G is ROHS3 compliant but is obsolete.

Q: What is the significance of the -3dB bandwidth specification?

A: The -3dB bandwidth indicates the frequency range over which the switch maintains specified performance. CD74HC4316ME4 specifies 200MHz, while MC74HC4316ADR2G, 74HC4316D,653, and NLV74HC4316ADR2G specify 160MHz. For applications operating below 160MHz, all parts are suitable. Applications requiring operation above 160MHz should use CD74HC4316M96 or CD74HC4316M to maintain the 200MHz bandwidth specification.

Q: Can substitute parts be mixed in the same design?

A: Mixing substitute parts with different on-state resistance values (170Ohm, 135Ohm, or 90Ohm) in the same circuit may introduce performance variations due to differences in channel matching and resistance characteristics. Designs should standardize on a single substitute part across all switching channels to maintain consistent performance and signal integrity.
