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.

UNITS
1. See Switching State Diagrams for VIN “ON” and VIN “OFF” Test Conditions.
2. Normally the minimum signal handling capability of the DG181 thru DG191 family is 20V peak to peak for the 75switches and 15V peak-
to-peak for the 30(refer ID and IS tests above).
3. For other Analog Signals, the following guidelines can be used: proper switch turn-off requires that V- VANALOG(peak) - VP where VP =
7.5V for the 80switches and VP = 5.0V for 75switches e.g., - 10V minimum (-peak) analog signal and a 75switch (VP = 5V), requires
that V- -10V -5V = -15V.
