DESCRIPTION/ORDERING INFORMATION

This 32-bit buffer/driver is designed for 1.65-V to 3.6-V V

The SN74LVCH322244A 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 eight 4-bit buffers, four 8-bit buffers, two 16-bit buffers, or one 32-bit buffer. It

provides true outputs and symmetrical active-low output-enable (OE) inputs.

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.

The outputs, which are designed to sink up to 12 mA, include equivalent 26-

undershoot.

To ensure the high-impedance state during power up or power down, OE should be tied to V

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

Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistors

with the bus-hold circuitry is not recommended.

This device is fully specified for partial-power-down applications using I

preventing damaging current backflow through the device when it is powered down.
