description
These 10-bit buffers and bus drivers provide
high-performance bus interface for wide data
paths or buses carrying parity.
The 3-state control gate is a 2-input AND gate with
active-low inputs so that if either output-enable
(OE1 or OE2) input is high, all ten outputs are in
the high-impedance state. The outputs are also 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 SN54BCT29828B is characterized for
operation over the full military temperature range
of − 55°C to 125°C. The SN74BCT29828B is
characterized for operation from 0°C to 70°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.
NOTE 1: The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
