16-to-8 Multiplexer/Demultiplexer
Bus Switch
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)
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.
