description
These 10-bit bus/MOS memory drivers provide a
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 outputs, which are designed to source or sink
up to 12 mA, include 33-series resistors to
reduce overshoot and undershoot.
The SN54BCT2828A is characterized for opera-
tion over the full military temperature range of
− 55°C to 125°C. The SN74BCT2828B is
characterized for operation from 0°C to 70°C.
