1. SN74HCT04PW Substitution Conclusion
The SN74HCT04PW can serve as a complete drop-in replacement for the original part number 74HCT04T14-13. Both are hex inverters with identical supply voltage range (4.5V to 5.5V), input thresholds (0.8V low / 2V high), and package (14-TSSOP). However, the TI device offers slight advantages in static power consumption (2µA vs. 20µA) and propagation delay (18ns at 5.5V vs. 22ns at 4.5V). Additionally, its output drive current is symmetrical (4mA for both high and low levels), whereas the original part has a slightly higher low-level output current (5.2mA). After substitution, system power consumption may decrease and signal transmission may be marginally faster, though low-level drive capability will be slightly reduced. This reduction remains within the standard HCT family specification and will not affect functional compatibility in typical digital circuits.
2. SN74HCT04PWT Substitution Conclusion
The SN74HCT04PWT is electrically and mechanically identical to the SN74HCT04PW. The suffix "T" typically denotes a tape-and-reel packaging option, with no differences in electrical characteristics or package dimensions. Therefore, the substitution conclusion is the same as for the SN74HCT04PW: it can directly replace the original part, with identical technical differences and impacts (lower static power, slightly faster propagation delay, and symmetrical output current). Only the packaging format should be verified to meet production SMT requirements.
