_________________General Description

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.
