Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and environmental compliance. Ensure the selected variant matches the required pinout and thermal specifications for your PCB layout. Cross-reference the part number with official onsemi documentation to validate availability status and lead times before finalizing procurement plans.

Selection Notes

Select this component when designing circuits that require noise-immune digital inversion or waveform conditioning. The Schmitt trigger functionality is essential for cleaning up distorted signals before further processing. Consider the 74ACT series compatibility with existing TTL-based systems while benefiting from CMOS power efficiency. Evaluate the DIP-14 package suitability for through-hole assembly requirements.

Part Context

This part belongs to the 74ACT logic family, which bridges the performance gap between standard 74LS and high-speed 74HC series. The ACT series maintains TTL-compatible input thresholds while offering faster switching speeds and lower power dissipation than LS counterparts. This specific model integrates six inverters, making it suitable for complex digital logic designs requiring multiple signal inversion stages within a single integrated circuit package.

Replacement Considerations

Direct replacements include MC74ACT14DR2G (SOIC-14) and MC74ACT14DG (SOIC-14). Verify pin compatibility and package dimensions when substituting surface-mount variants for through-hole DIP packages. Ensure electrical parameters such as propagation delay and output current capabilities meet design requirements.
