SN74ABT863 - 9-Bit Bus Transceivers With 3-State Outputs

The 'ABT863 devices are 9-bit transceivers designed for asynchronous communication between data buses. The control-function implementation allows for maximum flexibility in timing.

These devices allow noninverted 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. The outputs remain in the high-impedance state while the device is powered down.

When V_CC is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down. However, to ensure the high-impedance state above 2.1 V, OE\ should be tied to V_CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

The SN54ABT863 is characterized for operation over the full military temperature range of -55°C to 125°C.
The SN74ABT863 is characterized for operation from -40°C to 85°C.
