PI74AVC+16821

2.5V 20-Bit Bus Interface

Flip-Flop with 3-State Outputs

Description

Product Features

Pericom Semiconductors PI74AVC+ series of logic circuits are

produced using the Companys advanced submicron CMOS

technology, achieving industry leading speed.

PI74AVC+16821 is designed for low-voltage operation,

V_CC= 1.65V to 3.6V

True ±24mA Balanced Drive @ 3.3V

I_OFFsupports partial power-down operation

3.6V I/O Tolerant Inputs and Outputs

ThePI74AVC+16821isa20-bit businterfaceflip-flopdesignedfor

1.65V to3.6V V operation. Itcanbeusedastwo10-bitflip-flops

or one 20-bit flip-flop. The 20 flip-flops are edge-triggered D-type

flip-flops. On the positive transition of the clock (CLK) input, the

device provides true data at the Q outputs.

All outputs contain a patented DDC

(Dynamic Drive Control) circuit that reduces noise

without degrading propagation delay

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

outputsineitheranormallogicstate(HIGHorLOWlevel)orahigh-

impedance state. In the high-impedance state, the outputs neither

loadnordrivethebuslinessignificantly.Thehigh-impedancestate

and increased drive provide the capacity to drive bus lines without

the need for interface or pullup components.

Industrial operation: 40°C to +85°C

Available Packages:

56-pin 240 mil wide plastic TSSOP (A)

56-pin 173 mil wide plastic TVSOP (K)

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.
