MAX4534/MAX4535 19-1609 Rev 2 5/05 Fault-Protected, High-Voltage, Single 4-to-1/Dual 2-to-1 Multiplexers General Description Features The MAX4534 (single 4-to-1) and MAX4535 (dual 2-to- 40V Fault Protection with Power Off 1) fault-protected multiplexers operate with 4.5V to 25V Fault Protection with 15V Supplies 20V dual supplies or a +9V to +36V single supply. No Power-Supply Sequencing Required These multiplexers feature fault-protected inputs, rail- to-rail signal-handling capability, and overvoltage All Channels Off with Power Off clamping at 150mV beyond the rails. Both parts feature Rail-to-Rail Signal Handling 40V overvoltage protection with supplies off and 25V protection with supplies on. On-resistance is 400 max Output Clamped to Appropriate Supply Voltage and is matched between channels to 10 max. All digi- During Fault Condition tal inputs have TTL logic thresholds, ensuring 1.0k typ Output Clamp Resistance During TTL/CMOS-logic compatibility when using a single +12V or dual 15V supplies.

Signals on COM , EN, or A exceeding V+ or V- are clamped by internal diodes. Limit forward diode current to maximum current rating. Note 2: NO pins are fault-protected. Signals on NO exceeding -25V to +25V may damage the device during power-on conditions. When the power is off the maximum voltage range is -40V to +40V. 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.
