74LVC540A

OCTAL BUFFER/ LINE DRIVER WITH 3 STATE OUTPUTS

Description

The 74LVC540A is an octal inverting buffer/driver is designed for

driving bus lines or buffer memory address registers. The 3-state

control gate is a 2-input AND gate with active-low inputs so that, if

either output enable (OE1 or OE2) input is high, all eight outputs are in

the high-impedance state..These devices feature inputs and outputs

on opposite sides of the package that facilitate printed circuit board

layout.

The device is designed for operation with a power supply range of

1.65V to 3.6V.

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

output preventing damaging current backflow when the device is

powered down.
