CD74HCT4094M Equivalent & Substitute Parts

Part Overview

The CD74HCT4094M is an 8-stage shift register with tri-state output, manufactured by Texas Instruments in a 16-SOIC surface mount package. This component functions as a serial-to-parallel converter and is classified as a logic shift register IC. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain identical electrical specifications, package dimensions, and functional characteristics to ensure direct replacement capability.

Substitute Part Grouping Explanation

Substitution eligibility for the CD74HCT4094M is determined by strict equivalence across the following critical parameters: logic type (shift register), output type (tri-state), bit configuration (1 element, 8 bits), functional capability (serial to parallel conversion), supply voltage range (4.5V ~ 5.5V), package type (16-SOIC), and mounting method (surface mount). All substitute parts listed maintain these core specifications. Packaging format (tube, tape & reel, or cut tape) does not affect electrical or functional compatibility. Operating temperature range variations and product status (active, obsolete, or discontinued) are noted for procurement planning but do not preclude functional substitution when electrical parameters align.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring the CD74HCT4094M, the CD74HCT4094M96 (Texas Instruments, active status) is the primary direct substitute, offering identical electrical specifications and extended supply availability. The 74HCT4094D,118 (Nexperia USA Inc., active status) provides an alternative from an established manufacturer with current production status, though it specifies a narrower operating temperature range (-40°C to 125°C versus -55°C to 125°C). Both parts maintain ROHS3 compliance and MSL 1 rating.

For legacy system maintenance where the original temperature range (-55°C to 125°C) is required, the MC74HCT4094ADR2G (onsemi, last time buy status) remains available with matching specifications. The MC74HCT4094ADG and 74HCT4094D,112 are functionally equivalent but carry obsolete status, limiting long-term procurement viability.

All listed substitutes are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99, maintaining regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can CD74HCT4094M96 replace CD74HCT4094M directly on a PCB? A: Yes. Both parts are electrically identical 8-stage shift registers in 16-SOIC packages with matching pin configurations, supply voltage requirements (4.5V ~ 5.5V), and tri-state output characteristics. The difference is packaging format (tape & reel versus tube), which does not affect circuit performance.

Q: What is the difference between 74HCT4094D,112 and 74HCT4094D,118? A: Both are Nexperia 74HCT4094 shift registers in 16-SOIC packages with identical electrical specifications. The suffix designates packaging format and supplier designation: ,112 indicates tube packaging (obsolete status), while ,118 indicates tape & reel packaging (active status). Electrical performance is equivalent.

Q: Does the operating temperature range difference between -55°C to 125°C and -40°C to 125°C affect substitution? A: The narrower range (-40°C to 125°C) is suitable for standard industrial and commercial applications. Use the wider range (-55°C to 125°C) only if your application requires operation below -40°C. For most applications, the Nexperia 74HCT4094D,118 with active status is acceptable.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 compliance certification and MSL 1 (unlimited moisture sensitivity level), matching the original CD74HCT4094M specifications.

Q: Why is product status (active, obsolete, last time buy) important? A: Product status indicates procurement availability and long-term supply reliability. Active parts have ongoing production. Last time buy parts have limited remaining inventory. Obsolete parts may have restricted availability. For new designs, prioritize active status parts (CD74HCT4094M96 or 74HCT4094D,118).
