description/ordering information

This 16-bit buffer/driver is designed for 2.7-V to

3.6-V V

operation.

The SN74LVCZ16244A 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.

Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators

in a mixed 3.3-V/5-V system environment.

During power up or power down when V

is between 0 and 1.5 V, the device is in the high-impedance state.

However, to ensure the high-impedance state above 1.5 V, OE

should be tied to V

through a pullup resistor;

the minimum value of the resistor is determined by the current-sinking capability of the driver.
