Bus Switch with –2V Undershoot Protection
Description
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
