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 ’ABT827 provides

true data at the outputs.

When VCC is between 0 and 2.1 V, the device

is in the high-impedance state during power up

or power down. However, to ensure

the high-impedance state above 2.1 V, 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 SN54ABT827 is characterized for operation over the full military temperature range of −55°C to 125°C. The

SN74ABT827 is characterized for operation from −40°C to 85°C.
