_________________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 +25C or 10nA at +85C.
The digital input has 0.8V and 2.4V logic thresholds,
ensuring TTL/CMOS-logic compatibility when using a
single +5V supply.

at +25C.
Note 4: SOT and SC70 packaged parts are 100% tested at +25C. Limits at maximum and minimum rated temperature are guaran-
teed by design and correlation limits at +25C.
