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.
