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.

This is a stress rating only and functional operation of the device at these or any other conditions above those indi- cated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. Maximum Ratings (Above which the useful life may be impaired. For user guidelines, not tested.) Note: 1.
