74LVC1G17

SINGLE SCHMITT-TRIGGER BUFFER

Description

Pin Assignments

The 74LVC1G17 is a single 1-input Schmitt-trigger buffer with

a standard totem pole 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:

Y = A
