MAX4511/MAX4512/MAX4513 19-4760 Rev 1 8/02 Quad, Rail-to-Rail, Fault-Protected, SPST Analog Switches General Description Features The MAX4511/MAX4512/MAX4513 are quad, single- 40V Fault Protection with Power Off pole/single-throw (SPST), fault-protected analog switch- 36V Fault Protection with 15V Supplies es. They are pin-compatible with the industry-standard All Switches Off with Power Off nonprotected DG201/DG202/DG213. These new switch- es feature fault-protected inputs and Rail-to-Rail signal Rail-to-Rail Signal Handling handling capability. The normally open (NO ) and Output Clamped to Appropriate Supply Voltage normally closed (NC ) terminals are protected from overvoltage faults up to 36V during power-up or During Fault Condition No Transition Glitch power-down. During a fault condition, the NO or NC 175 max Signal Paths with 15V Supplies terminal becomes an open circuit and only nanoamperes No Power-Supply Sequencing Required of leakage current flow from the source, but the switch output (COM ) furnishes up to 10mA of the appropriate 4.5V to 18V Dual Supplies polarity supply voltage to the load. This ensures unam- +9V to +36V Single Supply biguous rail-to-rail outputs when a fault begins and ends. Low Power Consumption, <2mW On-resistance is 175 max and is matched between switches to 10 max. The off-leakage current is only Four Separately Controlled SPST Switches 0.5nA at +25C and 10nA at +85C. Pin-Compatible with Industry-Standard The MAX4511 has four normally closed switches. The DG411/DG412/DG413, DG201/DG202/DG213 MAX4512 has four normally open switches. The MAX4513 has two normally closed and two normally TTL- and CMOS-Compatible Logic Inputs with open switches. Single +9V to +15V or 15V Supplies These CMOS switches can operate with dual power supplies ranging from 4.5V to 18V or a single supply between +9V and +36V. Pin Configurations/ All digital inputs have +0.8V and +2.4V logic thresh- Functional Diagrams/Truth Tables olds, ensuring both TTL- and CMOS-logic compatibility when using 15V or a single +12V supply.

Signals on COM or 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. Signals on NC or NO exceeding -36V to +36V may damage the device. These limits apply with power applied to V+ or V-, or 40V with V+ = V- = 0. 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.
