2N7000  These N-Channel Enhancement Mode Field Effect Transistors.  These devices are used in many RASCAL GLX and GLK sound card interfaces, as they have been designed to minimize on-state resistance while providing rugged, reliable, and fast switching performance.  They can be used in most applications requiring  up to 400mA DC and can deliver pulsed currents up to 2A. These products are particularly suited for low voltage, low current applications.  Because of their insulated gate feature, they also perform a measure of isolation between gate and source.  2/ .99, 2N7000	This device is designed as a general purpose amplifier and switch. The useful dynamic range extends to 100 mA as a switch and to 100 MHz as an amplifier.
