Substitute Part Grouping Explanation

Substitution for the CD74HCT373M96G4 is determined by the following critical parameters:

Logic Type: D-Type Transparent Latch
Circuit Configuration: 8:8
Output Type: Tri-State
Voltage Supply Range: 4.5V ~ 5.5V
Package Type: 20-SOIC

Engineering Selection Recommendations

All substitute parts listed maintain the core functional parameters required for direct replacement: D-Type Transparent Latch logic, 8:8 circuit configuration, tri-state output, 4.5V to 5.5V supply voltage, and 20-SOIC package footprint.

CD74HCT373M96 and CD74HCT573M96 are parametrically equivalent to the original part and are manufactured by Texas Instruments with identical electrical characteristics and MSL rating of 1.

74HCT373D,653 from Nexperia USA Inc. offers improved propagation delay (14ns versus 35ns) and is actively produced with ROHS3 compliance.

MC74HCT373ADWR2G and MC74HCT373ADWG from onsemi provide active product status with comparable propagation delay (28ns) and full temperature range support (-55°C to 125°C). Both are ROHS3 compliant.

MC74HCT573ADWR2G from onsemi is functionally equivalent with 30ns propagation delay and active product status.

MM74HCT373WMX from Fairchild Semiconductor is actively produced with 25ns propagation delay and higher output current capability (7.2mA). Operating temperature range is limited to -40°C to 85°C.

All substitute parts are ROHS3 compliant and REACH unaffected.

Frequently Asked Questions (FAQ)

Q: Can CD74HCT373M96 directly replace CD74HCT373M96G4?

A: Yes. CD74HCT373M96 is the active production equivalent with identical electrical specifications, package type, and mounting configuration. The primary difference is product status (active versus discontinued) and packaging format (Tape & Reel versus bulk).

Q: What is the difference between CD74HCT373M96 and CD74HCT573M96?

A: Both parts are D-Type Transparent Latch ICs with identical electrical parameters and 20-SOIC packaging. The base product numbers differ (373 versus 573), indicating different internal logic configurations. Verify functional requirements before substitution.

Q: Are there temperature range limitations with any substitute?

A: MM74HCT373WMX has a reduced operating temperature range of -40°C to 85°C compared to the original -55°C to 125°C. All other substitutes maintain the full -55°C to 125°C range or equivalent.

Q: What does MSL rating mean for these parts?

A: Moisture Sensitivity Level (MSL) indicates the maximum time a component can be exposed to moisture before soldering. MSL 1 (unlimited) is less restrictive than MSL 3 (168 hours). Parts with MSL 3 require controlled storage conditions.

Q: Does propagation delay variation affect compatibility?

A: Propagation delay differences (14ns to 35ns) do not affect functional compatibility. Selection depends on timing requirements of the specific application. Faster propagation delay (lower ns value) provides improved performance margin.

Q: Are all substitutes available in the same packaging format?

A: All substitutes use 20-SOIC surface mount packages with identical footprints. Packaging formats (Tape & Reel, Tube, Bulk) differ but do not affect PCB compatibility.
