Description

This 9-bit bus transceiver SN74LVC863A is designed for 1.65-V to 3.6-V VCC operation.

The SN74LVC863A is designed for asynchronous communication between data buses. The control-functio implementation allows for maximum flexibility in timing.

This device SN74LVC863A 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.

The outputs SN74LVC863A are in the high-impedance state during power-up and power-down conditions. The outputs remain in the high-impedance state while the device is powered down.

SN74LVC863A 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.

To ensure the high-impedance state during power up or power down, SN74LVC863A OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

The SN74LVC863A is characterized for operation from 40°C to 85°C.
