16-BIT BUFFER/DRIVER
WITH 3-STATE OUTPUTS

clock
drivers,
and
The device can be used as four 4-bit buffers, two
8-bit buffers, or one 16-bit buffer. It provides true
outputs and symmetrical active-low output-enable
(OE) inputs.
To ensure the high-impedance state during power up
or power down, 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.
