High-Current, 25, SPDT, CMOS Analog Switches
General Description
The MAX4659/MAX4660 are medium voltage CMOS analog switches with a low on-resistance of 25 max specifically designed to handle large switch currents. With a switch capability of up to 200mA peak current and 150mA continuous current (MAX4660), and up to 1 5 0 m A peak current and 75mA continuous current (MAX4659), these parts can switch loads as low as 50. They can replace reed relays with a million times the speed and a virtually unlimited number of lifetime c y c l e s . Normal power consumption is only 3mW, w h e t h e r the switch is on or off. These parts are TTL/CMOS compatible and will switch any voltage within their power-supply range. T h e devices are single-pole/double-throw (SPDT) switches. The MAX4659/MAX4660 contain one normally closed (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 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 off-leakage current is only 1nA max at TA = +25°C. The MAX4659 is available in 8-pin µMAX and SO packages. The MAX4660 is available in thermally enhanced exposed paddle µMAX and SO packages.

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