74LVC1G126

SINGLE BUFFER GATE WITH 3-STATE OUTPUT

Description

The 74LVC1G126 is a single non-inverting buffer/bus driver with a

3-state output. The output enters a high impedance state when a

LOW-level is applied to the output enable (OE) pin. 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
