CD74HC4067M96 Equivalent & Substitute Parts

Part Overview

The CD74HC4067M96 is a 16:1 multiplexer/demultiplexer integrated circuit manufactured by Texas Instruments, designed for signal routing and switching applications in interface circuits. This single-circuit IC operates with a supply voltage range of 2V to 6V and features an on-state resistance of 160Ohm maximum, making it suitable for low-voltage, high-speed switching applications. The device is currently in active production status and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameters for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HC4067M96 is determined by the following critical parameters:

• Functional Configuration: 16:1 multiplexer/demultiplexer circuit with single circuit count
• Package Compatibility: 24-SOIC surface mount package (0.295", 7.50mm Width)
• Operating Temperature Range: -55°C ~ 125°C (TA)
• Supply Voltage Compatibility: Parts must operate within overlapping voltage ranges
• On-State Resistance: Maximum allowable on-state resistance for signal integrity
• Regulatory Compliance: RoHS3 compliance and REACH unaffected status

The identified substitute parts maintain the core 16:1 multiplexer functionality and 24-SOIC package format. Variations in on-state resistance, bandwidth, and supply voltage ranges reflect different semiconductor process technologies and design approaches within the same functional category.

Parameter Comparison

Engineering Selection Recommendations

CD74HC4067M96 (Texas Instruments) remains the primary selection for applications requiring the specified 2V to 6V supply voltage range, 160Ohm maximum on-state resistance, and 89MHz bandwidth performance. This part is in active production status with unlimited moisture sensitivity rating (MSL 1), providing maximum flexibility for storage and handling.

MC14067BDWG (onsemi) is a functional substitute for applications where the extended supply voltage range (3V to 18V) is beneficial and where the higher on-state resistance (280Ohm maximum) and lower bandwidth (15MHz) are acceptable trade-offs. This part maintains RoHS3 compliance and the same operating temperature range. The MSL 3 rating (168 hours) requires controlled storage conditions.

HEF4067BT,653 (NXP Semiconductors) is identified as a substitute based on functional equivalence as a 16:1 multiplexer/demultiplexer circuit. Detailed electrical parameter specifications for this part are not provided in the available data; therefore, compatibility assessment requires direct reference to the NXP datasheet for supply voltage, on-state resistance, and bandwidth specifications. This part maintains MSL 1 rating and is in active production status.

All three parts are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Frequently Asked Questions (FAQ)

Q: Can the MC14067BDWG replace the CD74HC4067M96 in a 2V to 6V supply application?

A: The MC14067BDWG operates within a 3V to 18V supply range. While the upper voltage limit accommodates 6V operation, the minimum 3V supply voltage excludes applications requiring 2V operation. Substitution is valid only for designs operating at 3V or higher.

Q: What is the impact of the higher on-state resistance in the MC14067BDWG?

A: The MC14067BDWG specifies 280Ohm maximum on-state resistance compared to 160Ohm for the CD74HC4067M96. This 120Ohm difference affects signal attenuation and power dissipation in switching applications. Applications with stringent signal integrity requirements or low-impedance loads may not tolerate this increase.

Q: Are all three parts available in the same 24-SOIC package?

A: The CD74HC4067M96 and MC14067BDWG are confirmed in 24-SOIC (0.295", 7.50mm Width) surface mount packages. The HEF4067BT,653 package specification is not provided in the available data; verification against the NXP datasheet is required before PCB layout commitment.

Q: What does MSL 3 (168 Hours) mean for the MC14067BDWG?

A: MSL 3 indicates the part must be used within 168 hours of package opening under controlled humidity conditions (typically ≤30% relative humidity at 25°C). The CD74HC4067M96 and HEF4067BT,653 with MSL 1 rating have unlimited shelf life after opening, providing greater handling flexibility.

Q: Which substitute part is recommended for new designs?

A: Selection depends on specific application requirements. For 2V operation or maximum bandwidth (89MHz), the CD74HC4067M96 is required. For extended supply voltage range with acceptable performance trade-offs, the MC14067BDWG is suitable. The HEF4067BT,653 requires datasheet verification for electrical parameter confirmation before design commitment.
