DESCRIPTION

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

3.6-V VCC operation.

The SN74ALVCH162244 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.

The outputs, which are designed to sink up to 12 mA, include equivalent 26-W resistors to reduce overshoot and

undershoot.

To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup

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

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.

The SN74ALVCH162244 is characterized for operation from -40°C to 85°C.
