Product Description
Data flow from A to Y is controlled by Output Enable (OE). The device
operates in the transparent mode when LE is HIGH. The A data is
latched if CLK is held at a high or low logic level. If LE is LOW, 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 PI74AVC16835 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.
