The MM74HC14 utilizes advanced silicon-gate CMOS technology to achieve the low power dissipation and high noise immunity of standard CMOS, as well as the capability to drive 10 LS-TTL loads. The 74HC logic family is functionally and pinout compat-
ible with the standard 74LS logic family. All inputs are protected from damage due to static discharge by internal diode clamps to V
CC and ground.
