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 ( or ) input is high, all ten outputs
are in the high-impedance state. The 'ABT2827 provide true data at
To ensure the high-impedance state during power up or power down,
should be tied
to VCC through a pullup resistor; the minimum value of the
resistor is determined by the current-sinking capability of the
The outputs, which are designed to source or sink up to 12 mA,
include equivalent 25-
series resistors to reduce overshoot and undershoot.
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
