Substitute Part Grouping Explanation

Substitution eligibility for the CD74ACT14MG4 is determined by the following critical parameters:

Base product number: 74ACT14
Logic configuration: 6-channel inverter with Schmitt trigger inputs
Package type: 14-SOIC surface mount
Supply voltage range: 4.5V ~ 5.5V
Output current capability: 24mA (high and low)
Input logic thresholds: 0.8V (low), 2V (high)
Compliance: ROHS3, MSL 1

Substitute parts must maintain identical logic functionality, package footprint, and electrical performance within the specified operating parameters. Variations in propagation delay, quiescent current, operating temperature range, and packaging format (tube, tape & reel, cut tape) are permitted when the core electrical and mechanical specifications align.

Engineering Selection Recommendations

For applications currently using the CD74ACT14MG4, the following active substitute parts are available:

Primary Substitutes (Texas Instruments): CD74ACT14M96 maintains full electrical and thermal compatibility with identical propagation delay and quiescent current specifications. This part is actively produced and available in tape & reel packaging.

Alternative Substitutes (onsemi): MC74ACT14DR2G and 74ACT14SCX are actively produced onsemi equivalents. Both parts meet the core electrical requirements with improved propagation delay performance (11.5ns and 10ns respectively). Operating temperature range is reduced to -40°C ~ 85°C, which is suitable for commercial and industrial applications but not for extended military temperature range requirements. MC74ACT14DG offers identical specifications to MC74ACT14DR2G in tube packaging format.

All substitute parts maintain ROHS3 compliance and MSL 1 rating. Selection should be based on packaging availability, lead time, and operating temperature requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can MC74ACT14DR2G replace CD74ACT14MG4 in all applications? A: MC74ACT14DR2G is electrically compatible for logic function and output drive capability. The operating temperature range differs: MC74ACT14DR2G operates from -40°C to 85°C, while CD74ACT14MG4 operates from -55°C to 125°C. Applications requiring extended temperature operation below -40°C or above 85°C require the Texas Instruments variants.

Q: What is the difference between CD74ACT14M96 and CD74ACT14M? A: Both parts are Texas Instruments products with identical electrical specifications. CD74ACT14M96 is supplied in tape & reel packaging, while CD74ACT14M is supplied in tube packaging. The core device functionality and performance are equivalent.

Q: Does 74ACT14SCX offer performance advantages? A: 74ACT14SCX has a lower quiescent current specification (2 µA versus 4 µA) and faster propagation delay (10ns versus 14.5ns). These represent performance improvements for power-sensitive and timing-critical applications. Operating temperature range is -40°C to 85°C.

Q: Are all substitute parts pin-compatible with CD74ACT14MG4? A: All substitute parts use the 14-SOIC package with identical pinout. Direct PCB footprint compatibility is maintained across all listed alternatives.

Q: What packaging formats are available for substitutes? A: CD74ACT14M96 is available in tape & reel format. MC74ACT14DR2G is available in cut tape and Digi-Reel format. 74ACT14SCX is available in cut tape and Digi-Reel format. MC74ACT14DG is available in tube packaging.
