Product Description

Pericom Semiconductors PI74ALVTC series of logic circuits are

produced using the Companys advanced 0.35 micron CMOS

technology, achieving industry leading speed.

The PI74ALVTC16721 is a 20-bit flip-flop with 3-state outputs

designed specifically for 1.65V to 3.6V V

operation. The device

is designed with edge-triggered D-type flip-flops with qualified

clock storage. On the positive transition of clock (CLK) input, the

device provides true data at the Q outputs, provided that the clock-

enable (CLKEN) input is LOW. If CLKEN is HIGH, no data is stored.

A buffered output-enable (OE) input can be used to place the

20 outputs in either a normal logic state (HIGH or LOW level) or a

high-impedance state. In the high-impedance state, the outputs

neither load nor drive the bus lines significantly. The high-impedance

state and increased drive provide the capacity to drive bus lines

without the need for interface or pullup components. OE does not

affect the internal operation of the flip-flops. Old data can be

retained or new data can be entered while the outputs are in the high-

impedance state.

To ensure the high-impedance state during power up or power

down, OE should be tied to V

through a pullup resistor; the

minimum value of the resistor is determined by the current-sinking

capability of the driver.

The family offers both I/O Tolerant, which allows it to operate in

mixed 1.65/3.6V systems, and "Bus Hold," which retains the data

inputs last state preventing "floating" inputs and eliminating the

need for pullup/down resistors.
