Product Description
Pericom Semiconductor鈥檚 PI5C series of logic circuits are produced
using the Company鈥檚 advanced submicron CMOS technology,
achieving industry leading performance.
The PI5C3306CD is a 5V, 2-bit Dual Side bus switch. It is intended
for PCI Hot-Plug applications. Industry leading advantages include
a propagation delay of 250ps that result from its 5-ohm channel
resistance and low I/O capacitance. The A-ports switch data to B
outputs and are bidirectional. The PI5C3306CD device has active
LOW enables.
When the switch is disabled, the A&B ports can handle up to 鈥?V
undershoot.
Applications
鈥?PCI Hot Plugging for live insertion
鈥?Memory bank sharing
