DG181 thru DG191

High-Speed Drivers with JFET Switch

April 1999

Features

Description

• Constant ON-Resistance for Signals to ±10V (DG182, The DG181 thru DG191 series of analog gates consist of 2

DG185, DG188, DG191), to ±7.5V (All Devices)

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.

• ±15V Power Supplies

• <2nA Leakage from Signal Channel in Both ON and

OFF States

• TTL, DTL, RTL Direct Drive Compatibility

• t_ON, t_OFF<150ns, Break-Before-Make Action

• Cross-Talk and Open Switch Isolation >50dB at 10MHz

(75Ω Load)
