1. MM74HCT04MTCX Substitution Conclusion
The MM74HCT04MTCX can fully replace the original part 74HCT04PW,112. Their key parameters are essentially identical: both use a 14-TSSOP package, operate from a 4.5V to 5.5V supply, and share the same input logic thresholds (0.8V/2.0V). The primary differences are that the MM74HCT04MTCX offers a slightly higher output drive current (4.8mA vs. 4mA) and a marginally longer propagation delay (20ns @5V vs. 19ns @4.5V, under slightly different test conditions). These variations have minimal impact in practical applications—the increased drive current may slightly improve fan-out capability, while the delay difference is negligible in standard HCT logic circuits and will not affect timing design in the vast majority of digital systems.
2. MC74HCT04ADTR2G Substitution Conclusion
The MC74HCT04ADTR2G can fully replace the original part 74HCT04PW,112 and offers some performance advantages. The package, supply voltage range, and logic levels are identical to the original. However, the quiescent current is reduced to 1μA (versus 2μA originally), which benefits low-power applications. The propagation delay is also improved, shortened to 17ns @5V (compared to 19ns @4.5V for the original), providing a slight increase in signal speed. The output drive current (4mA) matches the original part, ensuring compatibility without risk. This device maintains full electrical compatibility while delivering minor optimizations in power consumption and speed, making it a direct, enhanced drop-in replacement.
