Low-Voltage, Single-Supply, SPST CMOS Analog Switches
MAX4594-MAX4597 single-pole/single-throw (SPST) analog switches operate from single +2.0V +5.5V supply. MAX4594/MAX4596 switches normally open (NO), MAX4595/MAX4597 normally closed (NC). MAX4596/MAX4597 pinouts optimized highest SC70 package off-isolation available. These switches have on-resistance (RON), with flatness over analog signal range when powered from supply. MAX4594-MAX4597 offer 0.5nA leakage currents fast switching times less than 40ns. They packaged ultra-small 5-pin SC70 6-pin µDFN.

Applications Information
Analog Signal Levels
Analog signals range over supply voltage GND) with on-resistance changing very little over entire range (see Typical Operating Characteristics). MAX4594-MAX4597 bidirectional, pins used either inputs outputs.
Power-Supply Sequencing Overvoltage Protection
Proper power-supply sequencing recommended CMOS devices. Always apply before applying analog signals logic inputs, especially analog logic signals current limited. this sequencing possible, analog logic inputs current limited <20mA, small-signal diode (D1) shown Figure analog signal below GND, Adding protection diodes reduces analog signal range diode drop (about 0.7V) below diode drop above ground addition diodes does affect leakage. On-resistance increases small amount supply voltages. Maximum supply voltage (V+) must exceed Protection diodes also protect against some overvoltage situations. fault voltage absolute maximum rating analog signal input does damage device, even supply voltage below signal voltage.
