The mm74hc08 and Gates utilize advanced silicon-gate CMOS technology to achieve operating speeds similar to ls-ttl Gates with the low power consumption of standard CMOS integrated circuits. The HC08 has buffered outputs, providing high noise immunity and the ability to drive 10 ls-ttl loads. The 74HC logic family is functionally as well as pin-out compatible with the standard 74LS logic family. All inputs are protected from damage due to static discharge by internal diode clamps to vcc and ground.
