TARGET SPECIFICATION  
PI74EXP16345  
1.8V Registered 1-Bit to 4-Bit Address  
Driver w/3-State Outputs  
ProductDescription  
Product Features  
Pericom Semiconductor’s PI74EXP series of logic circuits are  
produced using the Company’s advanced submicron CMOS  
technology, achieving industry leading speed.  
• PI74EXP16345 is designed for low voltage operation,  
V
CC  
= 1.65V to 1.8V  
• I  
supports partial power down operation  
OFF  
ThePI74EXP16345isidealfordriving memorymodulesinsystems  
where multiple memory modules are used. One each of the four  
output banks drive a different module; modules can be added or  
removed without affecting the signal integrity of the other modules  
in the system. Dual clock enables (CEx) allow use of the device in  
high-speedmemoryinterleavingapplicationswheretheclockcanbe  
alternatelyenabledanddisabled, allowingtheaddresstobeheldfor  
additional cycles during memory access.  
• I/O Tolerant to 2.7V  
• All outputs contain Dynamic Impedance Control circuitry  
reducing noise without speed degradation  
• Industrial operation at –40°C to +85°C  
• Available Packages:  
– 56-pin 240 mil wide plastic TSSOP (A)  
– 56-pin 173 mil wide plastic TVSOP (K)  
Toensurethehigh-impedancestateduringpoweruporpowerdown,  
OE should be tied to V through a pullup resistor; the minimum  
CC  
value of the resistor is determined by the current sinking capability  
of the driver.
