MAXIM MAX4706, MAX4707 Technical data

General Description
The MAX4706/MAX4707 single-pole/single-throw (SPST) switches operate from a single 1.8V to 5.5V sup­ply. The MAX4706 is a normally closed (NC) switch and the MAX4707 is the normally open (NO) version. These switches provide 2on-resistance (RON) and 0.6 RONflatness with a +2.7V supply. These devices typi­cally consume only 0.02µA of quiescent current, mak­ing them suitable for use in low-power, portable applications. The MAX4706/MAX4707 feature low-leak­age currents over the entire temperature range, TTL/CMOS-compatible digital logic, and excellent AC characteristics.
The MAX4706/MAX4707 are offered in small 5-pin and 6-pin SC70 and 6-pin µDFN packages.

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.

Note 2: SC70 and µDFN packaged parts are 100% tested at +25°C. Limits across the full temperature range are guaranteed by
design and correlation.
Note 3: R
