19-1907; Rev 1; 11/03 Fault-Protected, Low-Voltage, Quad SPST Analog Switches Features 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. ♦ Fault-Protected 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. ♦ Single- and Dual-Supply Operation ________________________Applications Communication Systems Battery-Operated Systems Signal Routing Test Equipment Data-Acquisition Industrial and Process Control Systems ♦ ±12V Fault Protection with Power Off ♦ ±7V Fault Protection with ±5V Supplies ♦ +12V and -7V Fault Protection with +5V Supply ♦ +12V and -9V Fault Protection with +3V Supply ♦ Fault-Protected Digital Inputs May Exceed V+ Supply Rail ♦ All Switches Off with Power Off ♦ Rail-to-Rail Signal Handling ♦ Output Clamped to Appropriate Supply Voltages During Fault Condition ♦ 25Ω (max) RON at +25°C ♦ 1Ω (max) On-Resistance Match Between Channels ♦ Pin-Compatible with Industry-Standard MAX391/MAX392/MAX393 ♦ TTL- and CMOS-Compatible Logic Inputs Ordering Information PART TEMP RANGE PIN-PACKAGE MAX4711CUE 0°C to +70°C 16 TSSOP MAX4711CSE 0°C to +70°C 16 Narrow SO MAX4711CPE 0°C to +70°C 16 Plastic Dip MAX4711EUE -40°C to +85°C 16 TSSOP MAX4711ESE -40°C to +85°C 16 Narrow SO MAX4711EPE -40°C to +85°C 16 Plastic Dip Ordering Information continued at end of data sheet.

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. 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.

No Connection. Not internally connected. 13 13 13 V+ Detailed Description The MAX4711/MAX4712/MAX4713 differ considerably from traditional fault-protection switches, with several advantages. First, they are constructed with two parallel FET’s allowing very low on-resistance. Second, they allow signals on the NC_ or NO_ pins that are within or slightly beyond the supply rails to be passed through the switch to the COM terminal, allowing rail-to-rail signal operation. Third, when a signal on NC_ or NO_ exceeds the supply rails by about 150mV (a fault condition) the voltage on COM_ is limited to the same polarity supply voltage. Operation is identical for both fault polarities. During a fault condition, the NO_ or NC_ input becomes high impedance regardless of the switch state or load resistance. If the switch is on, the COM_ output current is supplied from V+ or V- by the clamp FET’s that are connected from COM to each supply. These FET’s can typically source or sink up to 15mA. When power is removed, the fault protection is still in effect. In this case, the NO_ or NC_ terminals are a virtual open circuit. The fault can be up to ±12V. The COM_ pins are not fault-protected, they act as normal CMOS switch terminals. If a voltage source is connected to any COM_ pin, it should be limited to the supply voltages. Exceeding the supply voltage will 10 Negative Supply Voltage Input. Connect to GND for single-supply operation. Positive Supply Input cause high currents to flow through the ESD-protected diodes, possibly damaging the device (see Absolute Maximum Ratings). Pin Compatibility These switches have identical pinouts to common nonfault-protected CMOS switches. Care should be exercised while considering them for direct replacements in existing printed circuit boards since only the NO_ and NC_ pins of each switch are fault-protected. Internal Construction Internal construction is shown in Figure 1, with the analog signal paths shown in bold. A single NO switch is shown; the NC configuration is identical except the logic-level translator is inverting. The analog switch is formed by the parallel combination of N-channel FET (N1) and P-channel FET (P1), which are driven on and off simultaneously according to the input fault condition and the logic-level state. Normal Operation Two comparators continuously compare the voltage on the NO_ (or NC_) pin with V+ and V-. When the signal on NO_ or NC_ is between V+ and V- the switch acts normally, with FETs N1 and P1 turning on and off in response to IN_ signals. The parallel combination of N1 and P1 forms a low-value resistor between NO_ (or ______________________________________________________________________________________ Fault-Protected, Low-Voltage, Quad SPST Analog Switches MAX4711/MAX4712/MAX4713 NORMALLY OPEN SWITCH CONSTRUCTION V+ P2 HIGH FAULT P1 COM_ NO_ (NC_) N1 LOW FAULT ON IN_ GND N2 V-ESD DIODE NC SWITCH Figure 1. Block Diagram NC_) and COM_ so that signals pass equally well in either direction. Positive Fault Condition When the signal on NO_ (or NC_) exceeds V+ by about 150mV, the high-fault comparator output is high, turning off FETs N1 and P1. This makes the NO_ (or NC_) input high impedance regardless of the switch state. If the switch state is “off”, all FETs are turned off and both NO_ (or NC_) and COM_ are high impedance. If the switch state is “on”, clamp FET P2 is turned on, sourcing current from V+ to COM_. Negative Fault Condition When the signal on NO_ (or NC_) exceeds V- by about 150mV, the low-fault comparator output is high, turning off FETs N1 and P1. This makes the NO_ (or NC_) input high impedance regardless of the switch state. If the switch state is “off”, all FETs are turned off and both NO_ (or NC_) and COM_ are high impedance. If the switch state is “on”, clamp FET N2 is turned on, sinking current from COM_ to V-. Transient Fault Response and Recovery When a fast rise-time or fall-time transient on NC_ or NO_ exceeds V+ or V-, the output (COM_) follows the input to the supply rail with only a few nanoseconds delay. This delay is due to the switch on-resistance and circuit capacitance to ground. When the input transient returns to within the supply rails, however, there is a 700ns output recovery delay time. These values depend on the COM_ output resistance and capacitance, and are not production tested or guaranteed. The delays are not dependent on the fault amplitude. Higher COM_ output resistance and capacitance increase recovery times. COM_ and IN_ Pins FETs N2 and P2 can source about ±15mA from V+ or V- to COM_ in the fault condition. Ensure that if the COM_ pin is connected to a low-resistance load, the absolute maximum current rating of 40mA is never exceeded both in normal and fault conditions. ______________________________________________________________________________________ 11 MAX4711/MAX4712/MAX4713 Fault-Protected, Low-Voltage, Quad SPST Analog Switches The COM_ pins do not have fault protection. Reverse ESD-protection diodes are internally connected between COM_, and V+ and V-. If a signal on COM_ exceeds V+ or V- by more than a diode drop, one of these diodes will conduct. The IN_ pin can exceed the positive supply voltage, but they can go below the negative supply by only a diode drop. The maximum voltage on these pins is 12V if operating from a single supply, regardless of the supply voltage (including 0 volts), and if operating from dual supplies, the maximum voltage is (V- + 12V). Fault-Protection Voltage and Power Off The maximum fault voltage on the NC_ or NO_ pins is ±12V with power off.
