PI74ALVTC16244  
1.8/2.5/3.3V 16-Bit Buffer/Driver  
with 3-State Outputs  
Product Features  
Product Description  
• PI74ALVTC family is designed for low voltage operation,  
VDD = 1.8Vto3.6V  
Pericom Semiconductor’s PI74ALVTC series of logic circuits  
are produced in the Company’s advanced 0.35 micron CMOS  
technology, achieving industry leading speed.  
• Supports Live Insertion  
The PI74ALVTC16244 buffer/driver is designed specifically to  
improve both the performance and density of 3-state memory  
address drivers, clock drivers, and bus-oriented receivers and  
transmitters.  
• 3.6V I/O Tolerant Inputs and Outputs  
• Bus Hold  
• HighDrive,-32/64mA@3.3V  
• Uses patented noise reduction circuitry  
• Power-off high impedance inputs and outputs  
• Industrial operation at –40°C to +85°C  
• Packagesavailable:  
Thedevicecanbeusedasfour4-bitbuffers,two8-bitbuffers,orone  
16-bit buffer. It provides true outputs and symmetrical active-low  
output-enable (OE) inputs.  
To ensure the high-impedance state during power up or power  
down, OE should be tied to Vdd through a pullup resistor; the  
minimum value of the resistor is determined by the current-sinking  
capability of the driver.  
–48-pin240milwideplasticTSSOP(A)  
–48-pin173milwideplastic TVSOP(K)  
–48-pin300milwideplastic SSOP(V)  
The family offers both I/O Tolerant, which allows it to operate in  
mixed 1.8/3.6V systems, and “Bus Hold,” which retains the data  
input’s last state whenever the data input goes to high-impedance,  
preventing “floating” inputs and eliminating the need for pullup/  
down resistors.
