General Description  
Features  
The MAX4644 is a single-pole/double-throw (SPDT)  
switch that operates from a single supply ranging from  
+1.8V to +5.5V Single-Supply Operation  
Rail-to-Rail Analog-Signal Range  
+1.8V to +5.5V. It provides low 4Ω on-resistance (R  
)

4Ω max (+5V Supply)  
8Ω max (+3V Supply)  
range. The MAX4644 offers fast switching times of less  
than 20ns while ensuring break-before-make operation.  
It typically consumes only 0.01μW of quiescent power,  
making it suitable for use in low-power, portable appli-  
cations.
