Description

Features, Applications

The DG417L/DG418L/DG419L precision, CMOS analog switches feature low on-resistance (RON = 35), guaranteed R ON matching between switches (3 max), and guaranteed RON flatness over the signal range (4 max). These switches are +3V logic-compatible when powered from 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 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 +36V or bipolar 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/DG418L/ DG419L are available in a tiny 8-pin �MAX, 8-pin SO, or convenient 8-pin plastic DIP. All products are rated at the extended temperature range to +85�C.

Note 1: Signals on COM, NO, or NC exceeding or V- are clamped by internal diodes. 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.
