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 V_CC 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 V_CC through a pullup resistor; the
minimum value of the resistor is determined by
the current-sinking capability of the driver.
