PI74AVC+16721

2.5V 20-Bit Flip-Flop

with 3-State Outputs

ProductDescription

Product Features

Pericom Semiconductor’s PI74AVC+ series of logic circuits are

produced using the Company’s advanced submicron CMOS

technology, achieving industry leading speed.

• PI74AVC+16721 is designed for low voltage operation,

V_CC= 1.65V to 3.6V

• True ±24mA Balanced Drive @ 3.3V

The PI74AVC+16721 is a 20-bit flip-flop with 3-state outputs

• I

designed specifically for 1.65V to 3.6V V

operation. The

• 3.6V I/O Tolerant inputs and outputs

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

thattheclock-enable(CLKEN)inputisLOW.If CLKENisHIGH,

no data is stored.

• All outputs contain a patented DDC

(Dynamic DriveControl) circuit that reduces noise without

degrading propagation delay.

• Industrial operation at –40°C to +85°C

• Available Packages:

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

retainedor newdatacanbeenteredwhiletheoutputsareinthehigh-

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
