DESCRIPTION

This 18-bit buffer and line driver is designed for

1.65-V to 3.6-V VCC operation.

This SN74ALVCH16825 improves the performance

and density of 3-state memory address drivers, clock

drivers, and bus-oriented receivers and transmitters.

The device can be used as two 9-bit buffers or one

18-bit buffer. It provides true data.

The 3-state control gate is a 2-input AND gate with

active-low inputs so that if either output-enable (OE1

or OE2) input is high, all nine affected outputs are in

the high-impedance state.

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 inputs at a valid logic level.

The SN74ALVCH16825 is characterized for operation from -40°C to 85°C.
