MAX4631/MAX4632/MAX4633 19-1515 Rev 0 7/99 Fault-Protected, High-Voltage, Dual Analog Switches General Description Features The MAX4631/MAX4632/MAX4633 high-voltage, dual Fault Protection analog switches are pin compatible with the industry-stan- 40V with Power Off dard DG401/DG403/DG405. They upgrade the existing 36V with 15V Supplies (MAX4631/MAX4633) devices with fault-protected inputs and Rail-to-Rail signal 25V with 15V Supplies (MAX4632) handling capabilities. The MAX4631/MAX4632/MAX4633s Rail-to-Rail Signal Handling normally open (NO) and normally closed (NC) terminals No Power-Supply Sequencing Required are protected from overvoltage faults up to 36V during power-up or power-down. During a fault condition, these All Switches Off with Power Off terminals become open circuit and only nanoamperes of Output Clamped to Appropriate Supply Voltage leakage current flow from the source, yet the switch output During Fault Condition No Transition Glitch (COM ) continues to furnish up to 18mA of the appropri- ate polarity supply voltage to the load. This ensures unam- 85 (max) Signal Paths with 15V Supplies biguous rail-to-rail outputs when a fault begins and ends. 4.5V to 18V Dual Supplies On-resistance is 85 (max) at +25C and is matched +9V to +36V Single Supply between switches to 6 (max). Off-leakage current is only 0.5nA at +25C and 5nA at +85C. Low Power Consumption: <6mW The MAX4631 has two NO single-pole/single-throw (SPST) Pin Compatible with Industry-Standard switches. The MAX4632 has two NO/NC single-pole/ DG401/DG403/DG405 double-throw (SPDT) switches. The MAX4633 has two NO TTL- and CMOS-Logic Compatible Inputs with double-pole/single-throw (DPST) switches. Single +9V to +15V, or 15V Supplies These CMOS switches operate with dual power supplies ranging from 4.5V to 18V or a single supply between +9V and +36V. All digital inputs have +0.8V and +2.4V Ordering Information logic thresholds, ensuring both TTL- and CMOS-logic compatibility when using 15V or a single +12V supply. PART TEMP.

Signals on COM to IN exceeding V+ or V- are clamped by internal diodes. Limit forward diode current to maximum current rating. Note 2: NC and NO pins are fault protected (see Electrical Characteristics). With power applied to V+ or V-, signals on NC or NO exceeding 25V (MAX4632) or 36V (MAX4631/MAX4633) may damage the device. With V+ = V- = 0, signals on NC or NO exceeding 40V may damage the device. 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.
