Description
3.3Volt, 24-Bit
Mux/Demux BusSwitch
Pericom Semiconductor鈥檚 PI3B series of logic circuits are produced
using the Company鈥檚 advanced 0.35 micron CMOS technology.
The PI3B16292 and PI3B162292 are 3.3 volt, 12-bit to 24-bit
Mux/Demux Bus switches designed with a low ON resistance
allowing inputs to be connected directly to outputs.
The PI3B162292 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.
