Product Description
Pericom Semiconductor’s PI3C series of logic circuits are produced
using the Company’s advanced submicron CMOS technology,
achieving industry leading performance.
The PI3C32160 is a 16- to 32-bit demultiplexer bus switch. Industry
leading advantages include a propagation delay of 500ps, resulting
from 9 ohms channel resistance and low I/O capacitance. A port
demultiplexes to either 1B or 2B and the switch is bidirectional.
Application
PCI Hot Plugging.
