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
inputs.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
2. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace
