The MAX4501/MAX4502 are single-pole/single-throw(SPST), low-voltage, single-supply, CMOS analog switches. The MAX4501 is normally open (NO). The MAX4502 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 is only 1nA at +25°C or 10nA at +85°C. The digital input has 0.8V and 2.4V logic thresholds,ensuring TTL/CMOS-logic compatibility when using a single +5V supply.
