Product Description
Pericom Semiconductor’s PI74AVC+ series of logic circuits are
produced using the Company’s advanced 0.35 micron CMOS
technology, achieving industry leading speed.
The 20-bit PI74AVC+16836 universal bus driver is designed
for 1.65V to 3.6V Vcc operation.
Data flow from A to Y is controlled by the Output Enable (OE) input.
The device operates in the transparent mode when the latch-enable
(LE) input is LOW. When LE is HIGH, the A data is latched if the
clock (CLK) input 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, but all the inputs are enabled and data is capable
of being stored in the register.
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.
