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 current is only 1nA at +25C or 10nA at +85C. 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.
