CD74ACT05QM96Q1 Equivalent & Substitute Parts

Part Overview

The CD74ACT05QM96Q1 is a 6-channel inverter IC with open drain output in 14-SOIC surface mount packaging, manufactured by Texas Instruments. This component is classified as obsolete, making substitute parts necessary for new designs and ongoing production requirements. The part operates within a 4.5V to 5.5V supply voltage range and is qualified to AEC-Q100 automotive standards. Equivalent and substitute parts maintain functional compatibility while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitution of the CD74ACT05QM96Q1 is based on strict equivalence of the following electrical and mechanical parameters:

Logic configuration: 6-channel inverter with open drain output
Supply voltage range: 4.5V ~ 5.5V
Input/output logic levels: Input low 0.8V, input high 2V, output low 24mA maximum
Quiescent current: 4 µA maximum
Package type: 14-SOIC surface mount
RoHS and MSL compliance: ROHS3 Compliant, MSL 1

The substitute parts CD74ACT05M96, MC74ACT05DG, and MC74ACT05DR2G maintain identical electrical specifications and package footprint. Differences in propagation delay and operating temperature ranges are noted but do not preclude functional substitution within the specified supply voltage and logic level parameters.

Engineering Selection Recommendations

CD74ACT05M96 is the primary substitute, manufactured by Texas Instruments with active product status. This part maintains identical electrical specifications and propagation delay characteristics to the original CD74ACT05QM96Q1, with extended lower operating temperature range (-55°C vs -40°C). ROHS3 compliance and MSL 1 rating are maintained.

MC74ACT05DG and MC74ACT05DR2G are onsemi equivalents with active product status. Both parts meet the core electrical requirements and package specifications. Operating temperature range is -40°C to 85°C, which is narrower than the original part. Propagation delay is improved at 8.5ns versus 10.8ns. These parts are suitable for applications within the -40°C to 85°C temperature window.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can MC74ACT05DG or MC74ACT05DR2G be used in applications requiring the full -40°C to 125°C operating range of the original CD74ACT05QM96Q1?

A: No. The onsemi parts are rated to -40°C to 85°C maximum. Applications requiring operation above 85°C must use CD74ACT05M96, which supports -55°C to 125°C.

Q: Are the propagation delay differences between CD74ACT05M96 (10.8ns) and the onsemi parts (8.5ns) significant for substitution?

A: The onsemi parts have faster propagation delay. For timing-critical applications, this difference must be evaluated against circuit requirements. Both values are within the 74ACT logic family specification.

Q: What is the difference between CD74ACT05M96 packaging (Cut Tape) and MC74ACT05DR2G packaging (Cut Tape & Digi-Reel)?

A: Packaging format affects handling and assembly processes. Both are surface mount 14-SOIC packages with identical footprints. Selection depends on procurement and assembly requirements.

Q: Are all substitute parts pin-compatible with the original CD74ACT05QM96Q1?

A: Yes. All parts use the 14-SOIC package with identical pinout and electrical characteristics within the specified parameters.

Q: Do the substitute parts maintain automotive qualification?

A: CD74ACT05M96 maintains AEC-Q100 automotive qualification. MC74ACT05DG and MC74ACT05DR2G do not list AEC-Q100 qualification in the provided specifications. Automotive applications must confirm qualification requirements with the manufacturer.
