– 1000-V Charged-Device Model (C101)

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

The SN74LVC863A 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.

The outputs 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.

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.
