Bus Switches

PI3CH digital bus switch products are ideally suited to address the operational requirements of next generation Servers, RAID, Super VGA, Memory Bank Switching, and Network/Telecom Backplanes.

The Low-voltage (2.5 V/3.3 V), High-bandwidth (500 MHz) Bus Switches offer expanded performance capabilities that work well with PCI-X, and DDR-I / DDR-2 memory standards, while simplifying the I/O migration from parallel to serial differential signaling standards. The 5 V I/O tolerance and beyond rail-to-rail capability makes the PI3CH Switch ideal for bridging legacy 5 V I/O based platforms to next generation 2.5 V/3 V systems.
