Low-Voltage, SPST, CMOS Analog Switches
_________________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.

Note 1:
Voltages exceeding V+ or GND on any signal terminal are clamped by internal diodes. Limit forward-diode current to
maximum current rating.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 2:
Algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.
Note 3:
Leakage parameters are 100% tested at maximum-rated hot operating temperature, and are guaranteed by correlation
at +25°C.
Note 4:
SOT and SC70 packaged parts are 100% tested at +25°C. Limits at maximum and minimum rated temperature are guaran-
teed by design and correlation limits at +25°C.
Note 5:
Guaranteed, not production tested.
