CD74HC4094M Equivalent & Substitute Parts

Part Overview

The CD74HC4094M is an 8-stage shift register with storage and tri-state bus output, manufactured by Texas Instruments in a 16-SOIC surface mount package. This logic component converts serial input data to parallel output format and is commonly used in digital control and data distribution applications. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain identical electrical characteristics, package compatibility, and functional specifications to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC4094M is determined by strict equivalence across the following critical parameters:

• Logic Type: Shift Register (8-bit, 1 element)
• Output Type: Tri-State bus register
• Function: Serial to Parallel conversion
• Supply Voltage Range: 2V ~ 6V
• Package: 16-SOIC surface mount form factor
• Base Product Number: 74HC4094

All substitute parts listed maintain these core electrical and mechanical specifications. Variations in product status, packaging format (Tube vs. Tape & Reel), operating temperature range, and moisture sensitivity level do not affect functional interchangeability in circuit applications. Automotive-grade variants with AEC-Q100 qualification provide additional reliability assurance for demanding environments but remain functionally equivalent for standard applications.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring immediate availability and long-term supply continuity, CD74HC4094M96 (Texas Instruments, Active status) or 74HC4094D,653 (Nexperia, Active status) are preferred substitutes. Both maintain the original operating temperature range and MSL rating while offering active product status and established supply channels.

For automotive and high-reliability applications, 74HC4094D-Q100J (Nexperia) and M74HC4094YRM13TR (STMicroelectronics) provide AEC-Q100 qualification, ensuring compliance with automotive industry standards. These variants are suitable for applications requiring enhanced quality assurance and traceability.

MC74HC4094ADR2G (onsemi) remains functionally equivalent but carries Last Time Buy status, indicating limited future availability. MC74HC4094ADG (onsemi) is classified as Obsolete and should be avoided for new designs or long-term production commitments.

All listed substitutes are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements equivalent to the original CD74HC4094M.

Frequently Asked Questions (FAQ)

Q: Can I use CD74HC4094M96 as a direct replacement for CD74HC4094M?

A: Yes. CD74HC4094M96 is functionally equivalent. Both are Texas Instruments 74HC4094 shift registers with identical electrical specifications, supply voltage range (2V ~ 6V), and 16-SOIC package. The primary difference is packaging format (Cut Tape & Digi-Reel vs. Tube) and product status (Active vs. Discontinued). Circuit performance is identical.

Q: What is the difference between the Nexperia 74HC4094D,653 and 74HC4094D-Q100J variants?

A: Both are Nexperia 74HC4094 shift registers in 16-SOIC packages with identical electrical performance. The 74HC4094D-Q100J includes AEC-Q100 automotive qualification and is supplied in Tape & Reel format, while 74HC4094D,653 is supplied in Cut Tape & Digi-Reel format. Operating temperature range differs slightly (-40°C ~ 125°C vs. -55°C ~ 125°C for the original), but both cover standard industrial and automotive temperature requirements.

Q: Is the STMicroelectronics M74HC4094YRM13TR suitable for my application?

A: M74HC4094YRM13TR is functionally equivalent for all 74HC4094 shift register applications. It provides AEC-Q100 automotive qualification and is available in Tape & Reel packaging. Note that MSL rating is 3 (168 Hours) compared to MSL 1 for other variants, which may affect moisture-sensitive storage requirements in high-humidity environments.

Q: Why should I avoid MC74HC4094ADG?

A: MC74HC4094ADG is classified as Obsolete by onsemi, indicating discontinued production and limited future availability. While functionally equivalent, it is not recommended for new designs or applications requiring long-term supply assurance. Active alternatives such as CD74HC4094M96 or 74HC4094D,653 are preferred.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting environmental regulations equivalent to the original CD74HC4094M.
