ADVANCE INFORMATION  
PI74AVC16821  
PI74AVCH16821  
20-Bit Bus Interface Flip-Flop  
with 3-State Outputs  
Product Features  
Description  
Pericom Semiconductor’s PI74AVC series of logic circuits are  
produced using the Company’s advanced 0.35 micron CMOS  
technology, achieving industry leading speed.  
• Designed for low voltage operation, VCC = 1.65V to 3.6V  
• Sub 2.0ns delays at 2.5V and 3.3V  
• Dynamic Impedance Control on outputs, current  
drive > ±24mA at 2.5VCC  
This 20-bit bus interface flip-flop can be used as two 10-bit flip-  
flops or one 20-bit flip-flops. The 20 flip-flops are edge-triggered  
D-type flip-flops. On the positive transition of the clock (CLK)  
input, the device provides true data at the Q outputs.  
• Patented noise reduction circuit  
• I/O Tolerant to 3.6V, Inputs and Outputs for  
mixed voltage systems  
A buffered output-enable (OE) input can be used to place the ten  
outputsineitheranormallogicstate(HIGHorLOWlevel)orahigh-  
impedance state. In the high-impedance state, the outputs neither  
loadnordrivethebuslinessignificantly.Thehigh-impedancestate  
and increased drive provide the capacity to drive bus lines without  
the need for interface or pullup components.  
• Supports live insertion  
• Industrial operation at -40°C to +85°C  
• Available Packages:  
– 48-pin 240 mil wide plastic TSSOP (A48)  
– 48-pin 173 mil wide plastic TVSOP (K48)  
OE does not affect the internal operation of the flip-flops. Old data  
can be retained or new data can be entered while the outputs are in  
the high-impedance state.  
To ensure the high-impedance state during power up or power  
down, OE should be tied to VCC through a pullup resistor; the  
minimum value of the resistor is determined by the current sinking  
capability of the driver.
