1. MM74HCT04MTCX Substitution Conclusion
From the perspectives of core functionality, logic levels, supply voltage, and package, the MM74HCT04MTCX can serve as a fully compatible drop-in replacement for the original SN74HCT04PWT. The key differences are its slightly larger maximum propagation delay (20ns @5V vs. 18ns @5.5V), which may marginally reduce timing margin in extremely high-speed applications, and its slightly stronger output drive capability (4.8mA vs. 4mA), offering a minor advantage in fan-out or capacitive load driving. Neither of these variances poses an issue in the vast majority of standard HCT logic circuit applications. Therefore, this part is a qualified direct substitute.
2. MC74HCT04ADTR2G Substitution Conclusion
The MC74HCT04ADTR2G is an excellent direct replacement for the original SN74HCT04PWT, offering superior performance in certain aspects. The differences include lower static power consumption (1µA vs. 2µA), resulting in improved power efficiency, and a shorter maximum propagation delay (17ns @5V vs. 18ns @5.5V), providing slightly faster switching speed under comparable conditions. Its output drive current matches the original part. All these variations constitute positive optimizations and introduce no compatibility concerns. Consequently, this model represents a high-performance alternative choice.
