~Siliconix .LII incorporated U421 SERIES N-Channel JFET Pairs The U421 Series are monolithic pairs of n-channel JFETs 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 (U421-3), high gain at low operating currents, and tight matching (10 mV for U421 and U424). Additionally, its TO-78 package is hermetically sealed and may be screened per MIL-S-19500. (See Section 1.)
