DUAL SCHMITT TRIGGER BUFFER

Description

Pin Assignments

The 74LVC2G17 is a dual Schmitt trigger buffer gate with

standard push-pull outputs. 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 I_OFF. The I_OFFcircuitry

disables the output preventing damaging current backflow

when the device is powered down.
