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 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 –2V undershoot during switch disable.
