PI74AVC16834 Datasheet PDF - Pericom Semiconductor Corporation

Product Description
The 18-bit PI74AVC16834 universal bus driver is designed for 1.8V 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.
The PI74AVC16834 bus driver is designed to drive an array of 133 MHz synchronous memory chips, with minimal undershoot/overshoot noise, and to meet the input signal rise/fall time requirement of memory chips.
