Description
Pericom Semiconductor鈥檚 PI5C series of logic circuits are produced
using the Company鈥檚 advanced 0.6 micron 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.
