CMOS Analog Switches  
General Description  
____________________________Features  
+1.8V to +5V Single-Supply Operation  
The MAX4645/MAX4646 single-pole, single-throw (SPST)  
analog switches feature a 2.5typical on-resistance  
Guaranteed R  
ON  
(R ) from a +5V supply. R  
is flat (0.4max) over the  
ON  
ON  
2.5max (5V supply)  
specified signal range. Each switch can handle Rail-to-  
Rail® analog signals. Off-leakage current is 0.25nA max at  
+25°C. These analog switches are ideal in low-distortion  
applications and are the preferred solution over mechani-  
cal relays in automated test equipment or applications  
where current switching is required. They have low power  
requirements, require less board space, and are more  
reliable than mechanical relays.

These switches operate from a +1.8V to +5V single sup-  
ply, making them ideal for use in battery-powered applica-  
tions. The MAX4645/MAX4646 have fast switching speeds  
of 12ns turn-on time (t ) and 8ns turn-off time (t  
).

The MAX4645 is a normally open (NO) switch, and the  
MAX4646 is a normally closed (NC) switch. Both are  
available in 5-pin SOT23, 6-pin SOT23, and 8-pin µMAX  
packages.
