74LVC14A
HEX INVERTERS WITH SCHMITT TRIGGER INPUTS
Description
The 74LVC14A provides six independent schmitt trigger inverter
buffers. The device is designed for operation with a power supply
range of 1.65V to 5.5V. The inputs are tolerant to 5.5V allowing this
device to be used in a mixed voltage environment. The device is fully
specified for partial power down applications using IOFF. The IOFF
circuitry disables the output preventing damaging current backflow
when the device is powered down.
The gates perform the positive Boolean function:
AY =
