HEX INVERTERS WITH SCHMITT TRIGGER INPUTS
Description
Pin Assignments
The 74HCT14 provides provides six independent Schmitt trigger input
inverters with standard push-pull outputs. The device is designed for
operation with a power supply range of 4.5V to 5.5V.
The gates perform the Boolean function:
Y = A
