CD74AC05M Equivalent & Substitute Parts

Part Overview

The CD74AC05M is a 6-channel inverter IC with open drain output in 14-SOIC surface mount packaging, manufactured by Texas Instruments. This logic component is discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications. The part operates across a wide supply voltage range and is suitable for general-purpose logic inversion applications requiring open drain output configuration.

Substitute Part Grouping Explanation

Substitution for the CD74AC05M is determined by strict equivalence across the following critical parameters:

Logic type: Inverter with 6 channels, 1 input per channel
Output configuration: Open drain
Package: 14-SOIC form factor
Mounting: Surface mount
Quiescent current: 4 µA maximum
Output current capability: 24mA low
RoHS3 compliance and MSL Level 1 rating

The substitute parts CD74AC05M96, MC74AC05DG, and MC74AC05DR2G meet these core requirements. Differences in supply voltage range and operating temperature reflect manufacturer-specific specifications but do not prevent functional substitution in applications designed for the CD74AC05M.

Engineering Selection Recommendations

CD74AC05M96 is the direct substitute from Texas Instruments, maintaining identical electrical specifications and operating temperature range (-55°C ~ 125°C). This part is currently active and available. Selection of this part eliminates any design verification requirements.

MC74AC05DG and MC74AC05DR2G are onsemi equivalents with identical logic function and output characteristics. Both parts operate within a narrower temperature range (-40°C ~ 85°C) and supply voltage range (2V ~ 6V), which is suitable for applications not requiring the extended -55°C lower temperature limit. Both are ROHS3 compliant and currently active. The MC74AC05DG is supplied in tube packaging, while MC74AC05DR2G is supplied in tape and reel format.

All substitute parts maintain the same 14-SOIC package footprint, quiescent current specification, and output current capability, ensuring direct functional replacement in existing designs.

Frequently Asked Questions (FAQ)

Q: Can MC74AC05DG or MC74AC05DR2G replace CD74AC05M in all applications?

A: Both onsemi parts are functionally equivalent for applications operating within the temperature range of -40°C to 85°C and supply voltage range of 2V to 6V. Applications requiring operation below -40°C or above 85°C must use CD74AC05M96 or the original CD74AC05M.

Q: What is the difference between CD74AC05M96 and the original CD74AC05M?

A: CD74AC05M96 is the active production equivalent with identical electrical and thermal specifications. The primary difference is packaging format: CD74AC05M is supplied in tube, while CD74AC05M96 is available in cut tape and Digi-Reel formats.

Q: Are the onsemi parts (MC74AC05DG, MC74AC05DR2G) pin-compatible with the Texas Instruments parts?

A: Yes. All substitute parts use the 14-SOIC package with identical pinout and functional behavior. Direct PCB substitution is possible without design modification.

Q: What is the difference between MC74AC05DG and MC74AC05DR2G?

A: Both parts are electrically identical. The difference is packaging format: MC74AC05DG is supplied in tube, while MC74AC05DR2G is supplied in tape and reel format for automated assembly.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. CD74AC05M96, MC74AC05DG, and MC74AC05DR2G are all ROHS3 compliant with MSL Level 1 rating.
