Product Description
Pericom Semiconductors PI3B series of logic circuits are produced using the Companys advanced sub micron CMOS technology, achieving industry leading performance.
The PI3B33X257 is a 3.3V, 24:12 multiplexer/demultiplexer with three-state outputs. Inputs can be connected to outputs with low on resistance (5 Ohm) with no additional ground bounce noise or propagation delay.

Product Features
• Permits Hot Insertion
• Near zero propagation delay
• 5 Ohm switches connect inputs to outputs
• Direct bus connection when switches are ON
• Ultra Low Quiescent Power (0.2µA Typical)
    - Ideally suited for notebook applications
• TTL - compatible control of input levels
• Fast switching speed - 4.5ns max.
• Packages available:
    -48-pin 150 mil wide plastic BQSOP (B)
