description
These
9-bit
transceivers
are
designed
for
asynchronous
communication
between
data
buses.
The
control-function
implementation
allows for maximum flexibility in timing.
These devices allow data transmission from the A
bus to the B bus or from the B bus to the A bus,
depending
upon
the
logic
levels
at
the
output-enable (OEBA and OEAB) inputs.
The outputs are in the high-impedance state
during power-up and power-down conditions. The
outputs remain in the high-impedance state while
the device is powered down.
The
SN54BCT29863B
is
characterized
for
operation over the full military temperature range
of – 55
°C to 125°C. The SN74BCT29863B is
characterized for operation from 0
°C to 70°C.
