MAX4551

The MAX4551/MAX4552/MAX4553 are quad, low-voltage,single-pole/single-throw (SPST) analog switches.Each switch is protected against ±15kV electrostatic discharge (ESD) shocks, without latchup or damage.On-resistance (100½ max) is matched between switches to 4½ max, and is flat (8½ max) over the specified signal range. Each switch can handle Rail-to-Rail® analog signals. The off-leakage current is only 1nA at+25°C and 10nA at +85°C.

The MAX4551 has four normally closed (NC) switches,and the MAX4552 has four normally open (NO) switches.The MAX4553 has two NC and two NO switches.These CMOS switches can operate with dual power supplies ranging from ±2V to ±6V or a single supply between +2V and +12V. They are fully specified for single +2.7V operation.
