19-1515; Rev 0; 7/99 Fault-Protected, High-Voltage, Dual Analog Switches General Description The MAX4631/MAX4632/MAX4633 high-voltage, dual analog switches are pin compatible with the industry-standard DG401/DG403/DG405. They upgrade the existing devices with fault-protected inputs and Rail-to-Rail® signal handling capabilities. The MAX4631/MAX4632/MAX4633’s normally open (NO) and normally closed (NC) terminals are protected from overvoltage faults up to 36V during power-up or power-down. Durin.

19-1515; Rev 0; 7/99 Fault-Protected, High-Voltage, Dual Analog Switches General Description The MAX4631/MAX4632/MAX4633 high-voltage, dual analog switches are pin compatible with the industry-standard DG401/DG403/DG405. They upgrade the existing devices with fault-protected inputs and Rail-to-Rail® signal handling capabilities. The MAX4631/MAX4632/MAX4633’s normally open (NO) and normally closed (NC) terminals are protected from overvoltage faults up to 36V during power-up or power-down. During a fault condition, these terminals become open circuit and only nanoamperes of leakage current flow from the source, yet the switch output (COM_) continues to furnish up to 18mA of the appropriate polarity supply voltage to the load. This ensures unambiguous rail-to-rail outputs when a fault begins and ends. On-resistance is 85Ω (max) at +25°C and is matched between switches to 6Ω (max). Off-leakage current is only 0.5nA at +25°C and 5nA at +85°C. The MAX4631 has two NO single-pole/single-throw (SPST) switches. The MAX4632 has two NO/NC single-pole/ double-throw (SPDT) switches. The MAX4633 has two NO double-pole/single-throw (DPST) switches. 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 logic thresholds, ensuring both TTL- and CMOS-logic compatibility when using ±15V or a single +12V supply.
