description

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 VCC 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 VCC 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.
