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.
The output drivers of this part have an embedded series-resistor.
For DIMM module design, no external series termination resistors
near the buffer drivers or any other termination resistors are
required. This feature simplifies DIMM module layout design, and
results in cost savings.
