HD74ALVC162244
16-bit Buffer / Driver with 3-state Outputs
ADE-205-204 (Z)
Preliminary
1st. Edition
January 1998
Description
The HD74ALVC162244 is designed specifically to improve both the performance and density of 3-state
memory address drivers, clock drivers, and bus oriented receivers and transmitters. 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
OE
(active-low output-enable) 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.
All outputs, which are designed to sink up to 12 mA, include equivalent 26
鈩?/div>
resistors to reduce overshoot
and undreshoot.
