description
These 10-bit buffers or bus 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 ’ABT2827 provide
true data at their outputs.
To ensure the high-impedance state during power
up or power down, OE should be tied to V_CC
through a pullup resistor; the minimum value of
the resistor is determined by the current-sinking
capability of the driver.

The outputs, which are designed to source or sink
up to 12 mA, include equivalent 25-Ω series
resistors to reduce overshoot and undershoot.
NC – No internal connection
The SN54ABT2827 is characterized for operation over the full military temperature range of –55°C to 125°C.
The SN74ABT2827 is characterized for operation from –40°C to 85°C.
