This 10-bit bus transceiver is designed for 1.65-V to 3.6-V V

operation.

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 this device as a translator in

a mixed 3.3-V/5-V system environment.

To ensure the high-impedance state during power up or power down, OE should be tied to V

through a pullup

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

This device is fully specified for partial-power-down applications using I

off

. The I

off

circuitry disables the outputs,

preventing damaging current backflow through the device when it is powered down.
