Maxim's MAX4655–MAX4658 are medium-voltageCMOS analog switches with low on-resistance of 10Ωmax, specifically designed to handle large switch currents.With a switch capability of up to 400mA peak currentand 300mA continuous current (MAX4655/MAX4656), and up to 300mA peak current and 150mA continuous current (MAX4657/MAX4658), these partscan switch loads as low as 25Ω. They can replace reedrelays with a million times the speed and virtually unlimitednumber of lifetime cycles. Normal power consumptionis only 3mW, whether the switch is on or off. Theseparts are TTL/CMOS compatible and will switch anyvoltage within its power-supply range.

These are SPST (single-pole/single-throw) switches.The MAX4655/MAX4657 are normally closed (NC),while the MAX4656/MAX4658 are normally open (NO).The difference between the MAX4655/MAX4656 andthe MAX4657/MAX4658 is in the power dissipation oftheir packages. Refer to the Absolute Maximum Ratingsand the Electrical Characteristics in the full data sheet.

The MAX4655–MAX4658 power-supply range is from±4.5V to ±20V for dual-supply operation and +9V to+40V for single-supply operation. These switches canoperate from any combination of supplies, within a 40VV+ to V- range. They conduct equally well in either directionand can handle rail-to-rail analog signals. The offleakagecurrent is only 1nA max at TA = +25°C. They areavailable in 8-pin µMAX®, TDFN, and SO packages, withexposed paddle options for high-power applications.
