MAX4712 General Description
The MAX4711/MAX4712/MAX4713 are fault-protected, Rail-to-Rail®, low-voltage analog switches featuring low on-resistance and guaranteed on-resistance flatness over the specified signal range. Due to the fault protection feature the analog switch input (NO_ or NC_) and output (COM_) pins are not symmetrical. The fault protection feature allows for the analog input to go beyond the plus or minus supplies without the device drawing excessive amounts of current from the analog inputs. When the analog inputs are driven beyond the supply rails when the switch is on, it will sense a fault and turn itself off and the analog switch output will be clamped to the same polarity supply as the input signal and will not go beyond the supply rails. This feature protects any electronic circuitry connected to the output from excessive voltages present on the analog inputs.
The MAX4711/MAX4712/MAX4713 are quad, singlepole/ single-throw (SPST) analog switches. The MAX4711 has four normally closed switches (NC), the MAX4712 has four normally open switches (NO), and the MAX4713 has two NO and two NC switches. Switching times are less than 125ns for tON, and less than 80ns for tOFF. These switches operate from a single +2.7V to +11V supply or from dual ±2.7V to ±5.5V supplies. All digital inputs have +0.8V to +2.4V logic thresholds, ensuring both TTL and CMOS logic compatibility when using ±4.5V to ±5.5V or single +4.5V to +11V supplies.

Note 1: COM_ pin is not fault-protected. Signals on COM_ exceeding V+ or V- are clamped by internal diodes. Limit forward diode current to maximum current rating.
Note 2: NO_ and NC_ pins are fault-protected. Signals on NO_ or NC_ exceeding -12V to +12V may damage device. These limits apply with V+ = V- = 0.
