Description
The 74LVC1G17 is a single 1-input Schmitt-trigger buffer with a
standard push-pull output. 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 gate
performs the positive Boolean function:
