Description
Pericom Semiconductor鈥檚 PI3B series of logic circuits are produced
using the Company鈥檚 advanced submicron CMOS technology.
The PI3B16292 is a 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.
A2 port is not externally connected and, as a result, has an internal
500 ohm pulldown resistor to ground.
