The MAX4511/MAX4512/MAX4513 are quad, single-pole/single-throw (SPST), fault-protected analog switches. They are pin-compatible with the industry-standard nonprotected DG201/DG202/DG213. These new switches feature fault-protected inputs and rail-to-rail signal handling capability. The 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, the NO_ or NC_ terminal becomes an open circuit and only nanoamperes of leakage current flow from the source, but the switch output (COM_) furnishes up to 10mA 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 175Ω max and is matched between switches to 10Ω max. The off-leakage current is only 0.5nA at +25°C and 10nA at +85°C.The MAX4511 has four normally closed switches. The MAX4512 has four normally open switches. The MAX4513 has two normally closed and two normally open switches.These CMOS switches can 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.ApplicationsAutomated Test Equipment (ATE)AvionicsData AcquisitionIndustrial and Process Control SystemsRedundant/Backup Systems

The MAX4514/MAX4515 are single-pole/single-throw (SPST), CMOS, low-voltage, single-supply analog switches with very low switch on-resistance. The MAX4514 is normally open (NO). The MAX4515 is normally closed (NC).These CMOS switches can operate continuously with a single supply between +2V and +12V. Each switch can handle rail-to-rail analog signals. The off-leakage current maximum is only 1nA at +25°C or 20nA at +85°C.All digital inputs have 0.8V to 2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a +5V supply.For pin-compatible parts for use with dual supplies, see the MAX4516/MAX4517.ApplicationsAudio/Video Signal RoutingBattery-Powered ApplicationsCell PhonesCommunication SystemsLow-Voltage Data AcquisitionModemsPCMCIA Cards

The MAX4516/MAX4517 are single-pole/single-throw (SPST), CMOS, low-voltage, dual-supply analog switches with very low switch on-resistance. The MAX4516 is normally open (NO). The MAX4517 is normally closed (NC).These CMOS switches can operate continuously with dual supplies between ±1V and ±6V. Each switch can handle rail-to-rail analog signals. The off-leakage current maximum is only 1nA at +25°C or 20nA at +85°C.The digital input is referenced to the positive power supply and is CMOS compatible.For pin-compatible parts for use with a single supply, refer to the MAX4514/MAX415.ApplicationsAudio/Video Signal RoutingBattery-Powered ApplicationsCell PhonesCommunication SystemsLow-Voltage Data AcquisitionModemsPCMCIA Cards
