MAX312F/MAX313F/MAX314F 19-2737 Rev 0 1/03 Quad, Rail-to-Rail, Fault-Protected, SPST Analog Switches General Description Features The MAX312F/MAX313F/MAX314F are quad, single- No Power-Supply Sequencing Required pole/single-throw (SPST), fault-protected analog switch- Rail-to-Rail Signal Handling es. They are pin compatible with the industry-standard nonprotected MAX312/MAX313/MAX314. These switch- All Switches Off with Power Off es feature fault-protected inputs and Rail-to-Rail signal- All Switches Off when V+ is Off and V- is On handling capability. All analog signal terminals are pro- tected from overvoltage faults up to 36V with power on 40V Fault Protection with Power Off and up to 40V with power off. During a fault condition, 36V Fault Protection with 15V Supplies the COM , NO , or NC terminal becomes an open cir- cuit and only microamperes of leakage current flow from Control Line Fault Protection from the source. On-resistance is 10 (max) and is matched V- - 0.3V to V- + 40V between switches to 0.5 (max) at +25C. Pin Compatible with Industry-Standard The MAX312F has four normally closed (NC) switches. DG411/DG412/DG413 The MAX313F has four normally open (NO) switches. The MAX314F has two NC and two NO switches. These 600ns (typ) Fault Response Time CMOS switches operate with dual power supplies rang- 10 (max) R with 15V Supplies ON ing from 4.5V to 20V or a single supply between +9V and +36V. All digital inputs have +0.8V and +2.4V logic 4.5V to 20V Dual Supplies thresholds, ensuring both TTL and CMOS logic com- +9V to +36V Single Supply patibility when using 15V or a single +12V supply.

Signals on COM , NO , and NC exceeding -36V to +36V may damage the device during power-on conditions. When the power is off, the maximum 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.
