The MAX4659/MAX4660 are medium voltage CMOSanalog switches with a low on-resistance of 25Ω max specifically designed to handle large switch currents.With a switch capability of up to 200mA peak currentand 150mA continuous current (MAX4660), and up to150mA peak current and 75mA continuous current(MAX4659), these parts can switch loads as low as50Ω. They can replace reed relays with a million times the speed and a virtually unlimited number of lifetimecycles. Normal power consumption is only 3mW,whether the switch is on or off. These parts areTTL/CMOS compatible and will switch any voltage withintheir power-supply range.

The devices are single-pole/double-throw (SPDT)switches. The MAX4659/MAX4660 contain one normallyclosed (NC) switch and one normally open (NO) switch.The MAX4659/MAX4660s' 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 eitherdirection and can handle rail-to-rail analog signals. Theoff-leakage current is only 1nA max at TA = +25°C. TheMAX4659 is available in 8-pin µMAX® and SO packages.The MAX4660 is available in thermally enhancedexposed paddle µMAX and SO packages.
