2. 74HCT04T14-13 Substitution Conclusion The 74HCT04T14-13 is functionally compatible with the original CD74HCT04PWRG4 and can serve as a replacement, but notable differences in certain performance parameters require attention. The core function, supply voltage, and package match the original, meeting the basic requirements for substitution. Key differences include: a significantly higher quiescent current of 20 µA, which is ten times that of the original part, leading to increased static power consumption in low-power or battery-operated applications; a slightly longer maximum propagation delay (22ns), resulting in marginally slower signal processing speed; and a slightly higher output low-level current (5.2mA vs. the original's 4mA), providing somewhat stronger sink capability when pulling the output low, though this typically does not pose a compatibility issue. Given these characteristics, this device is better suited for general-purpose applications where static power consumption and signal delay are not critical concerns.
