The PI5C3125C and PI5C3126C are 5V, 4-bit, 2-port bus switches. They are intended for PCI Hot-Plug applications. Industry leading advantages include a propagation delay of 250ps, resulting from its 5-ohm channel resistance and low I/O capacitance. The A-ports switch data to B outputs and are bidirectional. The PI5C3125C device has active LOW enables, and the PI5C3126C has active HIGH enables.
