  1. Circuits Supply Vishay SI2308DS Si2337DS
    For some ICs, supply voltages should be applied in a particular sequence. One example is the subscriber line interface circuit (SLIC), which, depending on the application, may require several negative and/or positive voltages. The larger voltages ...
