Description:

Pericom Semiconductor’s PI5C3390 and PI5C32390 are 16-to-8 multiplexer/demultiplexer bus switches with a low On-Resistance allowing inputs to be connected directly to outputs. The two enable inputs connect each of eight I/O to the common I/O pin. This multiplexer function can be used to select and route logic signals to form crossbar switches, isolate bus capacitance, or provide a zero delay switch connection. The bus switch creates no additional ground bounce noise or additional propagation delay. The PI5C32390 is designed with an internal 25-ohm resistor reducing noise reflection in high-speed applications.

Features:

• Near-Zero propagation delay

• Low noise, 25-ohm version(PI5C32390)

• 5-ohm switches connect inputs to outputs (PI5C3390)

• Direct bus connection when switches are ON

• Ultra-low quiescent power (0.2µA typical)

– Ideally suited for notebook applications

• Packaging (Pb-free & Green available):

– 28-pin 150-mil wide plastic QSOP (Q)
