Analog Switch Single SPDT 8-Pin uMAX T/R

The MAX4659/MAX4660 are medium voltage CMOS analog switches with a low on-resistance of 25O 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 150mA peak current and 75mA continuous current (MAX4659), these parts can switch loads as low as 50O. They can replace reed relays with a million times the speed and a 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 their power-supply range. The 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.
