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.
