Status Explanations for product status codes

Part Number Status
MAX4514 Active: In Production. See Ordering Information for details.
MAX4515 Active: In Production. See Ordering Information for details.


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.
