1. MC74HCT04ADTR2G Substitution Conclusion
The MC74HCT04ADTR2G serves as an excellent direct replacement for the SN74HCT04PW. Both devices are fully compatible in key parameters: supply voltage, logic levels, output drive capability, and package. The primary differences lie in the on‑semiconductor part’s static current (1 µA), which is half that of the original device, resulting in lower power consumption. Its maximum propagation delay (17 ns at 5 V) is slightly better than the original’s 18 ns at 5.5 V; however, given the different test voltage conditions, the actual performance is comparable. These variations have no adverse impact on circuit functionality, allowing for a seamless substitution.
2. 74HCT04T14‑13 Substitution Conclusion
The 74HCT04T14‑13 can be used as a conditional functional replacement for the SN74HCT04PW. While basic logic function, supply voltage, and package are identical, certain dynamic and static parameters show some degradation: first, the maximum propagation delay is longer (22 ns at 4.5 V), meaning signal speed at the nominal 5 V supply may be slower than the original; second, the static current (20 µA) is ten times higher, leading to significantly increased static power dissipation. An advantage is its slightly stronger low‑level output current (5.2 mA). This device is suitable for applications where speed and static power are not critical; prior to substitution, system timing and power budget should be evaluated to ensure compatibility.
