– 2000-V Human-Body Model (A114-A)

– 1000-V Charged-Device Model (C101)

The SN54LVC540A octal buffer/driver is designed for

2.7-V to 3.6-V V

operation, and the SN74LVC540A

octal buffer/driver is designed for 1.65-V to 3.6-V V

operation.

These devices are ideal for driving bus lines or buffer

memory address registers. These devices feature

inputs and outputs on opposite sides of the package

that facilitate printed circuit board layout.

Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators in a mixed 3.3-V/5-V system environment.
