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.
NC – No internal connection
When V
is between 0 and 2.1 V, the device is
CC
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 through a pullup resistor; the minimum
CC
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.

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
length of zero.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.

-
The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS

-
please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
