Product Description
Pericom Semiconductor’s PI5C series of logic circuits are produced
using the Company’s advanced submicron CMOS technology,
achieving industry leading performance.
The PI5C34171C is a 17 to 34-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. The A port can
handle up to –2V undershoot during switch disable.
Application
Provides PCI Hot Plugging
