Note: Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

Pericom Semiconductor's PI74ALVC series of logic circuits are produced using the Company's advanced 0.5 micron CMOS technology, achieving industry leading speed. The 18-bit PI74ALVC162834FD universal bus driver is designed for 2.3V to 3.6V VCC operation.

Data flow from A to Y is controlled by Output Enable (OE). The PI74ALVC162834FD operates in the transparent mode when LE is LOW. The A data is latched if CLK is held at a high or low logic level. If LE is HIGH, the A-bus of PI74ALVC162834FD is stored in the latch/flip-flop on the low-to-high transition of CLK. When OE is HIGH, the outputs are in the highimpedance state.

To ensure the high-impedance state PI74ALVC162834FD 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.
