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.<\/p>\n

Each gate performs the Boolean function Y = A AND B, outputting HIGH only when both inputs are HIGH. The HCT variant uses a special input stage with TTL-compatible threshold voltages (VIH = 2.0V, VIL = 0.8V), allowing direct interface with 5V TTL outputs from microcontrollers and legacy logic families. The output stage is standard CMOS push-pull, providing rail-to-rail output swings. Input clamp diodes protect against voltages exceeding VCC or below GND. The CMOS construction ensures minimal quiescent power consumption, while the TTL input levels make it a natural choice for bridging 5V TTL outputs to CMOS logic.","pin_description":"\n
