Analog Switches  
General Description  
Features  
Maxim’s MAX4655–MAX4658 are medium-voltage  
CMOS analog switches with low on-resistance of 10  
max, specifically designed to handle large switch cur-  
rents. With a switch capability of up to 400mA peak cur-  
rent 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 unlim-  
ited number of lifetime cycles. Normal power consump-  
tion 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.  
The 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 MAX4655–MAX4658 power-supply range is from  
4.5ꢀ to 20ꢀ for dual supply operation and ꢁꢂꢀ to  
ꢁ40ꢀ for single supply operation. These switches can  
operate from any combination of supplies, within a 40ꢀ  
ꢀꢁ to ꢀ- range. They conduct equally well in either direc-  
tion and can handle Rail-to-Rail® analog signals. The off-  
leakage current is only 1nA max at T = ꢁ25°C. They are  
A
available in 8-pin µMAX, QFN, and SO packages, with  
exposed pad options for high-power applications.
