LS5114 P-CHANNEL JFET
Linear Systems replaces discontinued Siliconix 2N5114
This analog switch is designed for inverting switching into inverting input of an Operational Amplifier. The hermetically sealed TO-18 package is well suited for hi-reliability and harsh environment applications. (See Packaging Information).
