Low-Voltage, 2, SPST, CMOS Analog Switches
General Description
T h e 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 s w i t c h e s provide 2 o n - r e s i s t a n c e (R ON) and 0.6 RON flatness with a +2.7V supply. These devices typically consume only 0.02µA of quiescent current, maki n g them suitable for use in low-power, portable applications. The MAX4706/MAX4707 feature low-leaka g e 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.

Limit forward-diode current to maximum current rating.
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.

MAX4706/MAX4707
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: RON flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the specified analog signal ranges. Note 4: Guaranteed by design. Note 5: Off-isolation = 20log10 (VO / VI), where VO is VCOM and VI is either VNC or VNO from the network analyzer.
