Description

General part information

SN74LVC540A-EP Series

The SN74LVC540A-EP octal buffer/driver is designed for 2.7-V to 3.6-V VCCoperation.

This device is ideal for driving bus lines or buffer-memory address registers. This device features inputs and outputs on opposite sides of the package that facilitate printed circuit board layout.

The 3-state control gate is a 2-input AND gate with active-low inputs so that, if either output-enable (OE1orOE2) input is high, all outputs are in the high-impedance state.
