CD74HC4316PW Equivalent & Substitute Parts

Part Overview

The CD74HC4316PW is a 4-circuit IC switch manufactured by Texas Instruments, configured as a SPST-NO (Single Pole Single Throw - Normally Open) multiplexer with 1:1 channel configuration. This component operates across a supply voltage range of 2V to 6V (single supply) or ±1V to ±5V (dual supply), with a maximum on-state resistance of 170Ohm and switching times of 37ns. The part is currently in Last Time Buy status, making equivalent substitutes necessary for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD74HC4316PW is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Switch circuit configuration: SPST - NO
• Number of circuits: 4
• Multiplexer/Demultiplexer circuit: 1:1
• Package type: 16-TSSOP surface mount
• Mounting compatibility: Surface mount with identical footprint dimensions (0.173", 4.40mm Width)
• Base product number: 74HC4316

Acceptable Variation Parameters:

• On-state resistance (Max): Substitutes must not exceed the original specification or introduce unacceptable performance degradation in the target application
• Supply voltage ranges: Substitutes must support the required operating voltage window
• Switch timing characteristics: Substitutes with faster or equivalent switching times are acceptable
• Operating temperature range: Substitutes must cover the required temperature window
• Compliance certifications: RoHS3 and MSL ratings must be maintained

The CD74HC4316PW has two qualified substitutes: CD74HC4316PWR (Texas Instruments, Tape & Reel packaging) and 74HC4316PW,118 (Nexperia USA Inc., Tape & Reel packaging). Both maintain the core 74HC4316 base product number and identical package footprint, ensuring direct PCB compatibility.

Parameter Comparison

Engineering Selection Recommendations

CD74HC4316PWR (Texas Instruments): This substitute is the primary recommendation for direct replacement of the CD74HC4316PW. It maintains identical electrical specifications, operating temperature range (-55°C ~ 125°C), and supply voltage parameters. The only difference is packaging format (Tape & Reel versus Tube), which does not affect component functionality or PCB compatibility. Product status is Active, ensuring long-term availability. RoHS3 compliance and MSL rating are maintained.

74HC4316PW,118 (Nexperia USA Inc.): This substitute offers improved performance characteristics in specific parameters while maintaining core functionality. On-state resistance is reduced to 135Ohm (versus 170Ohm), switch times are faster (16ns versus 37ns), and channel capacitance is lower (4.6pF versus 5pF). Single supply voltage range extends to 10V (versus 6V). However, the operating temperature range is narrower (-40°C ~ 125°C versus -55°C ~ 125°C), and channel-to-channel matching tolerance is slightly wider (6Ohm versus 5Ohm). This substitute is suitable for applications where the narrower temperature range is acceptable and where improved switching performance is beneficial. Product status is Active.

Selection between these substitutes depends on application-specific requirements: use CD74HC4316PWR for direct replacement with identical specifications, or use 74HC4316PW,118 when improved switching performance and lower on-state resistance are advantageous and the operating temperature range is compatible with system requirements.

Frequently Asked Questions (FAQ)

Q: Can CD74HC4316PWR be used as a direct replacement for CD74HC4316PW?

A: Yes. CD74HC4316PWR is electrically and functionally identical to CD74HC4316PW. Both are manufactured by Texas Instruments with the same 74HC4316 base product number, identical electrical specifications, and the same 16-TSSOP package footprint. The only difference is packaging format (Tape & Reel versus Tube), which does not affect component performance or PCB assembly compatibility.

Q: What are the key differences between the Texas Instruments and Nexperia substitutes?

A: The Nexperia 74HC4316PW,118 offers improved switching performance (16ns versus 37ns) and lower on-state resistance (135Ohm versus 170Ohm). However, it has a narrower operating temperature range (-40°C ~ 125°C versus -55°C ~ 125°C) and slightly wider channel-to-channel matching tolerance (6Ohm versus 5Ohm). Both maintain identical package footprint and core SPST-NO 4-circuit configuration.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 16-TSSOP package with identical footprint dimensions (0.173", 4.40mm Width) and the same base product number (74HC4316), ensuring direct PCB compatibility without layout modifications.

Q: What is the significance of the Last Time Buy status for CD74HC4316PW?

A: Last Time Buy status indicates that Texas Instruments will discontinue this specific part number. Existing inventory is limited to 1401 pieces. For ongoing production requirements, migration to an active substitute (CD74HC4316PWR or 74HC4316PW,118) is necessary to ensure supply continuity.

Q: Which substitute should be selected for applications requiring the full -55°C ~ 125°C temperature range?

A: CD74HC4316PWR must be selected for applications requiring operation at temperatures below -40°C. The Nexperia substitute (74HC4316PW,118) operates only to -40°C minimum and is not suitable for extended low-temperature applications.

Q: Are there any compliance or certification differences between the substitutes?

A: No. All three parts maintain identical RoHS3 compliance status and Moisture Sensitivity Level (MSL) rating of 1 (Unlimited). Compliance certifications are equivalent across all substitutes.
