Micross LSJ174 P-channel jfet Datasheet

LSJ174
P-CHANNEL JFET
Linear Systems replaces discontinued Siliconix J174
The LSJ174 is a single P-Channel JFET switch
This p-channel analog switch is designed to provide low
on-resistance and fast switching. When used in
combination with the complimentary J/SST111 nchannel family, the LSJ174 simplifies series-shunt
switching applications
