Fairchild 54F 74F132 Data Handbook
Summary
Optimize your circuit design with this high-reliability Quad 2-Input NAND Schmitt Trigger IC. Engineered to provide sharp, jitter-free output signals by employing built-in positive feedback and level shifting circuitry, it maintains signal integrity even when facing noise or extreme temperature variations. This manual provides comprehensive technical details, including electrical characteristics, absolute maximum ratings, detailed pin assignments, and ordering information for robust system integration. Essential for engineers building stable digital logic applications requiring superior noise immunity and wide operational tolerances across multiple industry standards (TTL/CMOS).
