ADVANCE INFORMATION

PI74AVC16721

PI74AVCH16721

20-Bit Flip-Flop with

3-State Outputs

ProductDescription

Product Features

Pericom Semiconductors PI74AVC series of logic circuits are

produced using the Companys advanced 0.35 micron CMOS

technology, achieving industry leading speed.

· Designed for low voltage operation,

V_CC= 1.65V to 3.6V

· Sub 2.0ns delays at 2.5V and 3.3V

· Dynamic Impedance Control on outputs,

current drive > ±24mA at 2.5V_CC

This 20-bit flip-flop is designed with edge-triggered D-type flip-

flopswithqualifiedclockstorage.Onthepositivetransitionofclock

(CLK) input, the device provides true data at the Q outputs,

providedthattheclock-enable(CLKEN)inputisLOW. IfCLKEN

is HIGH, no data is stored.

· Patented noise reduction circuit

· I/O Tolerant to 3.6V, Inputs and Outputs for

mixed voltage systems

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

neitherloadnordrivethebuslinessignificantly.Thehigh-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.

· Supports live insertion

· Industrial operation at -40°C to +85°C

· Available Packages:

48-pin 240 mil wide plastic TSSOP (A48)

48-pin 173 mil wide plastic TVSOP (K48)

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

down, OE should be tied to V through a pullup resistor; the

minimumvalue of the resistor is determined by the current-sinking

capability of the driver.

The PI74AVCH16721 has Bus Hold which retains the data inputs

last state whenever the data input goes to high-impedance

preventing floating inputs and eliminating the need for pullup/

down resistors.
