LSJ174
P-CHANNEL JFET
Linear Systems replaces discontinued Siliconix J174
The LSJ174 is a single P-Channel JFET switch
FEATURES
This p-channel analog switch is designed to provide low
DIRECT REPLACEMENT FOR SILICONIX J174
LOW ON RESISTANCE
LOW GATE OPERATING CURRENT
FAST SWITCHING
ABSOLUTE MAXIMUM RATINGS
@ 25°C (unless otherwise noted)
on-resistance and fast switching. When used in
combination with the complimentary J/SST111 n-
channel family, the LSJ174 simplifies series-shunt
switching applications
