The PI3C3125WE Digital Bus Switch IC 4 Bit 2 Port Bus Switch from Diodes Incorporated is an advanced bus switch designed for high-speed, low power, and low-voltage data transmission applications. This switch contains 4-way bidirectional ports and allows simultaneous bidirectional data transmission between two different buses. It operates with a voltage supply of 3.3V and features a low on resistance of 0.4 Ohm. The device also features a high switching performance with a total delay time of tPHL/tPLHMAX of 10 / 10 ns, and a propagation delay of tPD_UP/tPD_DWN_MAX of 10 / 10 ns. This switch is highly useful for data transfer and switching of high bandwidth signals in a wide range of machines, such as PCs, cell phones, set top boxes, networking, telecommunications, and consumer electronics.
