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 VCC

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-W 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 85°C.
