Product Features  
ProductDescription  
• PI74ALVTC16652isdesignedforlowvoltageoperation,  
Pericom Semiconductor’s PI74ALVTC series of logic circuits are  
produced using the Company’s advanced 0.35 micron CMOS  
technology, achieving industry leading speed.

• Uses patented noise reduction circuitry  
• Power-off high impedance inputs and outputs  
• Industrial operation at –40°C to +85°C  
• Packagesavailable:  
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.

LogicBlockDiagram  
Data on the A or B bus, or both, can be stored in the internal D flip-  
flopsbylow-to-hightransitionsattheappropriateclock(CLKABor  
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,  
whenallotherdatasourcestothetwosetsofbuslinesareinthehigh-  
impedance state, each set of bus lines remains at its last level  
configuration.

Toensurethehigh-impedancestateduringpoweruporpowerdown,  
OEBA should be tied to Vcc through a pull-up resistor and OEAB  
should be tied to GND through a pull-down resistor; the minimum  
value of the resistor is determined by the current-sinking current  
sourcing capability of the driver.

The family offers both I/O Tolerant, which allows it to operate in  
mixed 1.65/3.6V systems, and “Bus Hold,” which retains the data  
input’s last state preventing “floating” inputs and eliminating the  
need for pullup/down resistors.
