DESCRIPTION/ORDERING INFORMATION
This 16-bit buffer/driver is designed for 1.65-V to
3.6-V V_CC operation.
The SN74ALVC16244A is designed specifically to
improve 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 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.
