19-4168; Rev 0; 2/09 Signal-Line Overvoltage Protector for Low-Voltage Devices .. General Description - 28V Protection on EXT - Extended ESD Protection ±4kV IEC 61000-4 Contact on EXT Features The MAX9940 signal-line overvoltage protector for lowvoltage digital munication ports provides protection against high-voltage faults and ESD strikes. The MAX9940 is especially useful for sensitive munication protocols such as Maxim 1-Wire ® that cannot afford standard means of fault protection, such as large series resistors or large line capacitances. The MAX9940 operates from a single supply voltage of +2.2V to +5.5V and consumes only 13µA of quiescent supply...
