Product Description

Pericom Semiconductors PI74ALVC series of logic circuits are produced using the Companys 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 device 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 is stored in the latch/flip-flop on the low-to-high transition of CLK. When OE is HIGH, the 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.
