74HCT08N – TBC

Overview

The Nexperia 74HCT08N is a high-speed CMOS quad 2-input AND gate, designed to implement combinatorial logic functions with predictable timing characteristics. Its primary strength lies in its TTL-compatible input levels while leveraging the low power consumption of CMOS technology, a critical design consideration for battery-powered or thermally constrained systems. However, designers must carefully manage its relatively high propagation delay (11 ns typical) when interfacing with high-speed digital buses where setup and hold times are paramount, as this can limit its suitability for ultra-fast clocking applications without careful buffering or pipeline stages.
