_______________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.
