PI5C32161C
16-Bit to 32-Bit, Demux PCI Hot-Plug
Bus Switch with 聳2V Undershoot Protection
Product Description
Pericom Semiconductor聮s PI5C series of logic circuits are produced
using the Company聮s advanced submicron CMOS technology,
achieving industry leading performance.
The PI5C32161C is a 16- to 32-bit demultiplexer bus switch. It is
intended for PCI Hot-Plug applications. Industry leading advantages
include a propagation delay of 250ps, resulting from 5-Ohm channel
resistance, and low I/O Capacitance. A port demultiplexes to either
1B and 2B or to both. The switch is bidirectional. Precharge bias
voltage is provided on B ports to minimize live insertion noise. The
A port can handle up to 聳2V undershoot during switch disable.
