MAXIM MAX312FESE+T

The MAX312F/MAX313F/MAX314F are quad, single-pole/single-throw (SPST), fault-protected analog switches pin-compatible with the industry-standard unprotected MAX312/MAX313/MAX314. These switches feature fault-protected inputs and rail-to-rail signal handling. All analog signal terminals withstand overvoltage faults up to ±36V with power on and up to ±40V with power off. Under fault conditions, the COM_, NO_, or NC_ terminals go to an open-circuit state with only microampere-level leakage current flowing from the source. On-resistance is 10Ω (maximum) with switch-to-switch matching of 0.5Ω (maximum) at +25°C.

The MAX312F has four normally closed (NC) switches. The MAX313F has four normally open (NO) switches. The MAX314F has two NC and two NO switches. These CMOS switches operate from dual supplies ranging from ±4.5V to ±20V or single supplies from +9V to +36V. All digital inputs feature +0.8V and +2.4V logic thresholds, ensuring TTL and CMOS logic compatibility when using ±15V or a single +12V supply.
