Overview
U421 HIGH INPUT IMPEDANCE MONOLITHIC DUAL N-CHANNEL JFET
Linear Systems replaces discontinued Siliconix U421
The U421 is a high input impedance Monolithic Dual N-Channel JFET
The U421 monolithic dual n-channel JFET is designed to provide very high input impedance for differential amplification and impedance matching.
Among its many unique features, this series offers operating gate current specified at -250 fA.
The U421 is a direct replacement for discontinued Siliconix U421.
The hermetically sealed TO-71 & TO-78 packages are well suited for military applications.
The 8 Pin P-DIP and 8 Pin SOIC provide ease of manufacturing, and the symmetrical pinout prevents improper orientation.
