Low-Voltage, Dual-Supply, SPST,
CMOS Analog Switches
General Description
The MAX4503/MAX4504 are low-voltage, dual-supply,
single-pole/single-throw (SPST), CMOS analog switch-
es. The MAX4503 is normally open (NO). The MAX4504
is normally closed (NC).
These CMOS switches can operate continuously with
dual supplies between ±1.V and ±6V. Each switch can
handle rail-to-rail analog signals. The off-leakage cur-
rent is only 1nA at +25°C or 10nA at +85°C.
The digital input is CMOS-logic compatible when using
±5V supplies. A unique logic input architecture allows
this even though the parts have no ground pin.
For single-supply operation, use the MAX4501/
MAX4502, which are pin-for-pin equivalents.

Note 1:
Voltages on any signal terminal exceeding V+ or V- 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.

The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.
Guaranteed, not production tested.
Leakage parameters are 100% tested at maximum rated hot operating temperature, and guaranteed by correlation at +25°C.
SOT packaged parts are 100% tested at +25°C. Limits at maximum and minimum rated temperature are guaranteed by
design and correlation limits at +25°C.
