Overview
Semiconductor DG181 thru DG191 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.
