The SST174 is a single P-Channel JFET switch
Linear Systems replaces discontinued Siliconix SST174

This p-channel analog switch is designed to provide low on-resistance and fast switching. When used in combination with the complimentary J/SST111 n-channel family, the SST174 simplifies series-shunt switching applications.
