16-to-8 Multiplexer/Demultiplexer Bus Switch
1
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.
