PI74AUC16244  
1.8V 16-Bit Buffer/Driver  
with 3-State Outputs  
Features  
Description  
• PI74AUC16244 is designed for low-voltage operation,  
Pericom Semiconductor’s PI74AUC series of logic circuits are  
produced using the Company’s advanced submicron CMOS  
technology, achieving industry leading speeds.  
V
= 0.8V to 2.7V, optimized at 1.8V.  
CC  
• 3.6V I/O Tolerant inputs and outputs  
• I supports partial power-down operation  
The PI74AUC16244 is a 16-bit buffer driver designed specifically  
to improve both the performance and density of 3-state memory  
address drivers, clock drivers and bus-oriented receivers and  
transmitters.  
OFF  
• Latch-Up Performance exceeds 100mA per JESD 78  
• ESD Protection Exceeds JESD 22  
– 2000V Human-Body Model (A114-B)  
– 200V Machine Model (A115-A)  
The device can be used as four 4-bit buffers, two 8-bit buffers, or  
one16-bitbuffer.Itprovidesnon-invertingoutputsandsymmetrical  
active-low output-enable OE inputs.  
• Industrial operation: –40°C to +85°C  
To ensure the high-impedance state during power-up or power  
• Packaging:  
– 48-pin TSSOP (A)  
– 48-pin TSSOP (K)  
-down, OE should be tied to V through a pull-up resistor; the  
CC  
minimum value of the resistor is determined by the current-sinking  
ability of the driver.
