MAX4512 General Description
The MAX4511/MAX4512/MAX4513 are quad, singlepole/ 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 175½ max and is matched between switches to 10½ 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.

Note 1: COM_ and IN_ pins are not fault protected. 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.
