PI74ALVTC16601  
2.5V, 18-Bit Universal Bus Transceiver  
with 3-State Outputs  
ProductFeatures  
ProductDescription  
• PI74ALVTC16601isdesignedforlowvoltageoperation,  
Pericom Semiconductor’s PI74ALVTC series of logic circuits are  
produced using the Company’s advanced 0.35 micron CMOS  
technology, achieving industry leading speed.

=1.65Vto3.6V  
• Supports Live Insertion  
The PI74ALVTC16601 uses D-type latches and D-type flip-flops  
with 3-state outputs to allow data flow in transparent, latched, and  
clocked modes.  
• 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:  
Data flow in each direction is controlled by Output Enable (OEAB  
andOEBA),LatchedEnable(LEABandLEBA),andClock(CLKAB  
andCLKBA)inputs.TheclockcanbecontrolledbytheClockEnable

are active. When OEAB is HIGH, the outputs are in the high-  
impedance state.
