WILLSEMI WAS3157B-6/TR

The WAS3157B is a high performance, single pole double throw (SPDT) CMOS analog switch for bus switching or audio switching applications. It features high bandwidth up to 400MHz at -3dB and low on-resistance (5.5Ω Typ.). The SEL pin has overvoltage protection that allows voltages above VCC, up to 7.0V to be present on the pin without damage or disruption of operation of the part, regardless of the operating voltage. The WAS3157B is also featured with smart circuitry to minimize VCC leakage current even when SEL control voltage is lower than VCC supply voltage. In other word, there is no need of additional device to shift SEL level to be the same as that of VCC in real application. The WAS3157B is available in standard SOT-363(SC-70-6L) package. Standard product is Pb-Free and halogen-Free.
