ProductDescription

Product Features

Pericom Semiconductors PI74AVC+ series of logic circuits are

produced using the Companys advanced submicron CMOS

technology, achieving industry leading speed.

PI74AVC+16652 is designed for low-voltage operation,

V_CC= 1.65V to 3.6V

True ±24mA Balanced Drive @ 3.3V

The PI74AVC+16652 is a 16-bit bus transceiver and register

designedforlow1.65V to3.6VV_CCoperation.Itconsistsof D-type

flip-flopsandcontrolcircuitryarrangedformultiplexedtransmission

of data directly from the data bus or from the internal storage

registers. The device can be used as two 8-bit transceivers or one

16-bittransceiver.

supports partial power-down operation

3.6V I/O Tolerant Inputs and Outputs

All outputs contain a patented DDC

(Dynamic DriveControl) circuit that reduces noise without

degrading propagation delay.

Complementary Output Enable (OEAB and OEBA) inputs are

provided to control the transceiver functions. Select Control (SAB

and SBA) inputs are provided to select whether real-time or stored

dataistransferred.Alowinputlevelselectsreal-timedata,andahigh

input level selects stored data. Circuitry used for Select Control

eliminates the typical decoding glitch that occurs in a multiplexer

during the transition between stored and real-time data.

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)

LogicBlockDiagram

Data on the A or B bus, or both, can be stored in the internal D flip-

flops by low-to-high transitions at the appropriate clock (CLKAB

or CLKBA) inputs regardless of the levels on the Select Control or

Output Enable inputs. When SAB and SBA are in the real-time

transfer mode, it also is possible to store data without using the

internal D-type flip-lops by simultaneously enabling OEAB and

OEBA.Inthisconfiguration,eachoutputreinforcesitsinput.Thus,

when all other data sources to the two sets of bus lines are in the

high-impedance state, each set of bus lines remains at its last level

configuration.

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

down, OEBA should be tied to V through a pull-up resistor and

OEAB should be tied to GND through a pull-down resistor; the

minimumvalue of the resistor is determined by the current-sinking

current sourcing capability of the driver.
