DESCRIPTION/ORDERING INFORMATION

This 16-bit buffer/driver is designed for 1.65-V to

3.6-V VCC operation.

The SN74ALVCH16244 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 VCC through a blank

pullup resistor; the minimum value of the resistor is

determined by the current-sinking capability of the blank

driver.
