نظرة عامة على المنتج
The 74HCT08D from Nexperia is a quad 2-input AND gate with TTL-compatible input levels in an SOIC-14 package. Inputs include clamp diodes for overvoltage interfacing. Operating from 4.5V to 5.5V with 11 ns propagation delay, it provides CMOS low power consumption with TTL input thresholds, making it ideal for mixed 5V TTL/CMOS systems and glue logic.
