description
The ’ABT16825 devices are 18-bit buffers and line
drivers designed specifically to improve both the
performance and density of 3-state memory
address drivers, clock drivers, and bus-oriented
receivers and transmitters. These devices can be
used as two 9-bit buffers or one 18-bit buffer. They
provide true data.
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 nine affected
outputs are in the high-impedance state.
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,
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.
