High-Current, 10, SPST, CMOS Analog Switches
General Description
M a x i m ' s MAX4655MAX4658 are medium-voltage CMOS analog switches with low on-resistance of 10 max, specifically designed to handle large switch currents. With a switch capability of up to 400mA peak curr e n t and 300mA continuous current (MAX4655/ MAX4656), and up to 300mA peak current and 150mA continuous current (MAX4657/MAX4658), these parts can switch loads as low as 25. They can replace reed relays with a million times the speed and virtually unlimited number of lifetime cycles. Normal power consumption is only 3mW, whether the switch is on or off. These parts are TTL/CMOS compatible and will switch any voltage within its power-supply range. These are SPST (single-pole/single-throw) switches. T h e MAX4655/MAX4657 are normally closed (NC), while the MAX4656/MAX4658 are normally open (NO). The difference between the MAX4655/MAX4656 and the MAX4657/MAX4658 is in the power dissipation of their packages. Refer to the Absolute Maximum Ratings and the Electrical Characteristics. The MAX4655MAX4658 power-supply range is from ±4.5V to ±20V for dual supply operation and +9V to +40V for single supply operation. These switches can operate from any combination of supplies, within a 40V V+ to V- range. They conduct equally well in either direction and can handle Rail-to-Rail® analog signals. The offleakage current is only 1nA max at TA = +25°C. They are available in 8-pin µMAX, QFN, and SO packages, with exposed pad options for high-power applications. o High Continuous Current Handling 300mA (MAX4655/MAX4656) 150mA (MAX4657/MAX4658) o High Peak Current Handling 400mA (MAX4655/MAX4656) 300mA (MAX4657/MAX4658) o 10 max On-Resistance (±15V supplies) o VL not Required o 1 max RON Flatness over Specified Signal Range o Rail-to-Rail Signal Handling o +12V Single Supply or ±15V Dual Supply Operation o Pin Compatible with DG417, DG418

Note 1: Signals on NC, NO, COM, or IN exceeding V+ or V- will be 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.
