description

The SN74LVC861A is designed for asynchronous communication between data buses. The control-function

implementation allows for maximum flexibility in timing.

This device allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending on

the logic levels at the output-enable (OEAB and OEBA) inputs.

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.

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

The SN74LVC861A is characterized for operation from –40

°C to 85°C.
