J177
J177 is Switching manufactured by Micross.
J177 P-CHANNEL JFET
Linear Systems replaces discontinued Siliconix J177
The J177 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 bination with the plimentary J/SST111 nchannel family, the J177 simplifies series-shunt switching applications .
