The SN54LVC540A octal buffer/driver is designed for 2.7-V to 3.6-V VCC operation, and the SN74LVC540A octal buffer/driver is designed for 1.65-V to 3.6-V VCC 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.
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 outputs are in the high-impedance state.
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
