The DG417L precision, CMOS analog switches feature low on-resistance (R_ON = 35Ω), guaranteed R_ON matching between switches (3Ω max), and guaranteed R_ON flatness over the signal range (4Ω max). 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 also offer low off-leakage current over temperature (less than 5nA at +85°C).

The DG417Lare single-pole/single-throw (SPST) switches. The DG417L is normally closed, and the DG418L is normally open. Switching times are less than 175ns for t_ON and less than 185ns for t_OFF. These devices operate with a single +9V to +36V or bipolar ±4.5V to ±20V supplies.

The digital input has a +0.8V logic-low threshold and a +2.0V logic-high threshold, ensuring +3V TTL and CMOS-logic compatibility. The DG417L are available in a tiny 8-pin µMAX®, 8-pin SO, or convenient 8-pin plastic DIP. All products are rated at the extended temperature range of -40°C to +85°C.
