CD74HC4067E Equivalent & Substitute Parts

Part Overview

The CD74HC4067E is a 16:1 multiplexer/demultiplexer integrated circuit manufactured by Texas Instruments, designed for signal routing and switching applications in digital systems. This device features a single circuit configuration with 160Ohm on-state resistance and operates across a 2V to 6V supply voltage range. The CD74HC4067E is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, design updates, and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the CD74HC4067E is determined by strict equivalence across electrical and mechanical parameters. The primary substitution criterion is the base product number 74HC4067, which defines the functional architecture (16:1 multiplexer/demultiplexer with identical switching characteristics). All substitute parts must maintain:

Identical multiplexer/demultiplexer configuration (16:1)
Identical on-state resistance (160Ohm maximum)
Identical channel-to-channel matching specification (8.5Ohm)
Identical supply voltage range (2V ~ 6V)
Identical switching time specifications (51ns, 49ns maximum)
Identical bandwidth performance (-3dB at 89MHz)
Identical channel capacitance values (5pF, 50pF)
Identical leakage current specification (800nA maximum)
Identical operating temperature range (-55°C ~ 125°C)

The CD74HC4067E uses through-hole mounting in a 24-DIP package. Substitutes may employ alternative packaging technologies (surface mount) provided all electrical parameters remain unchanged. Product status (active vs. obsolete) and inventory availability inform selection priority but do not affect functional equivalence.

Engineering Selection Recommendations

The CD74HC4067M96 is the direct functional equivalent to the CD74HC4067E. Both devices share identical electrical specifications across all switching, timing, and signal integrity parameters. The primary distinction is packaging format: the CD74HC4067E employs through-hole 24-DIP technology, while the CD74HC4067M96 uses surface-mount 24-SOIC technology.

Selection between these parts depends on board design requirements. Through-hole mounting (CD74HC4067E) is suitable for breadboard prototyping, legacy PCB designs, and applications requiring mechanical robustness. Surface-mount technology (CD74HC4067M96) is appropriate for high-density PCB layouts, automated assembly processes, and modern production environments.

The CD74HC4067M96 holds active product status with substantial inventory availability (45,557 pieces), whereas the CD74HC4067E is obsolete with limited stock (2,100 pieces). Both devices maintain ROHS3 compliance and unlimited moisture sensitivity classification, ensuring regulatory and environmental compatibility across applications.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC4067M96 directly replace the CD74HC4067E in existing designs?

A: Electrical substitution is complete. The CD74HC4067M96 maintains identical switching characteristics, timing specifications, and signal integrity parameters. Physical substitution requires PCB redesign due to packaging differences (through-hole vs. surface-mount). Adapter solutions or manual rework may be necessary for legacy boards.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is valid when the following parameters match: 16:1 multiplexer/demultiplexer configuration, 160Ohm on-state resistance, 8.5Ohm channel-to-channel matching, 2V to 6V supply voltage range, 51ns/49ns switching times, 89MHz bandwidth, 5pF/50pF channel capacitance, 800nA maximum leakage current, and -55°C to 125°C operating temperature range.

Q: Does packaging format affect electrical performance?

A: No. The 24-DIP and 24-SOIC packages contain identical die and internal circuitry. Packaging differences affect PCB layout, assembly method, and board space requirements only. Electrical performance remains unchanged.

Q: Are there compliance or certification differences between these parts?

A: Both the CD74HC4067E and CD74HC4067M96 maintain ROHS3 compliance, unlimited MSL classification, and identical regulatory status. No compliance or certification differences exist.

Q: Why is the CD74HC4067E classified as obsolete?

A: Obsolescence reflects Texas Instruments' product lifecycle management. The CD74HC4067M96 represents the current active production equivalent, offering superior manufacturing support and supply chain availability. Functional capability remains unchanged.
