Description
Pericom Semiconductor聮s PI5C series of logic circuits are produced
using the Company聮s advanced submicron CMOS technology.
The PI5C16292 and PI5C162292 are 12-bit to 24-bit Mux/Demux Bus
switches designed with a low ON resistance allowing inputs to be
connected directly to outputs.
The PI5C162292 device has a built-in 25-ohm series resistor to
reduce noise resulting from reflections, thus eliminating the need for
an external terminating resistor.
A2 port is not externally connected and, as a result, has an internal
500-ohm pulldown resistor to ground.
