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 currentsinking capability of the driver.
