DG181-DG191
High-Speed Drivers with JFET Switch
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.
