These switches are +3V logic-compatible when powered from ±15V or ±12V supplies. The switches conduct equally well in either direction, and feature low charge injection and low power consumption. The DG417L/DG418L/DG419L also offer low off-leakage current over temperature (less than 5nA at +85°C). The DG417L/DG418L are single-pole/single-throw (SPST) switches. The DG417L is normally closed, and the DG418L is normally open. The DG419L is singlepole/double-throw (SPDT) with one normally closed switch and one normally open switch. Switching times are less than 175ns for tON and less than 185ns for tOFF. These devices operate with a single +9V to +36V or bipolar ±4.5V to ±20V supplies.

Limit forward current to maximum current ratings. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The older DG417/DG418/DG419 devices require a proper power-supply sequence of V+, VL, then V-. Otherwise, it is necessary to add signal diodes to the circuit in order to prevent potential latchups. The new DG417L/DG418L/DG419L devices eliminate the need for a VL input and allow any power-up sequence. Do not exceed the absolute maximum ratings because stresses beyond the listed ratings may cause permanent damage to the devices. ______________________________________Test Circuits/Timing Diagrams (continued) +3V V+ LOGIC INPUT 0 V+ NC +10V COM VOUT NO RL 300Ω IN 0.9 x VOUT VCOM LOGIC INPUT CL 35pF DG419L GND VV- tD CL INCLUDES FIXTURE AND STRAY CAPACITANCE.
