PI74AVC+16652  
2.5V 16-Bit Bus Transceiver and  
Register 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+16652 is designed for low-voltage operation,  
VCC = 1.65V to 3.6V  
• True ±24mA Balanced Drive @ 3.3V  
The PI74AVC+16652 is a 16-bit bus transceiver and register  
designedforlow1.65V to3.6VVCC operation.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.  
• I  
supports partial power-down operation  
OFF  
• 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)

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  
CC  
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.
