MM74HCT14
Hex Inverting Schmitt Trigger
General Description
The MM74HCT14 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 74HCT logic family is functionally and pinout compati-
ble with the standard 74LS logic family. All inputs are pro-
tected from damage due to static discharge by internal
diode clamps to V
CC
and ground.
