High-Speed Drivers with JFET Switch
Description
The DG181 thru DG191 series of analog gates consist of 2
or 4 N-channel junction-type field-effect transistors (JFET)
designed to function as electronic switches. Level-shifting
drivers enable low-level inputs (0.8V to 2V) to control the
ON-OFF state of each switch. The driver is designed to
provide a turn-off speed which is faster than turn-on speed,
so that break-before-make action is achieved when
switching from one channel to another. In the ON state, each
switch conducts current equally well in both directions. In the
OFF condition, the switches will block voltages up to 20V
peak-to-peak. Switch-OFF input-output isolation 50dB at
10MHz, due to the low output impedance of the FET-gate
driving circuit.
