Product Description

Pericom Semiconductor’s PI74ALVC series of logic circuits

are produced in the Company’s advanced 0.5 micron CMOS

technology, achieving industry leading speed.

The 16-bit PI74ALVC162334 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.

When LE is HIGH, the A data is latched if CLK is held at a high

or low logic level. If LE is HIGH, the A-data 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.

The outputs have equivalent 26 ohm series 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.
