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.
NC – No internal connection
The SN54ABT863 is characterized for operation over the full military temperature range of –55°C to 125°C.
