CONTROL B  
The MAX14774/MAX14779 analog switches support  
analog signals up to ±25V using a single 3.0V to 5.5V  
supply. The MAX14774 has four independent analog  
switches with separate control inputs, while the  
MAX14779 has two SPDT analog switches. Both parts  
support separate logic level inputs, allowing flexible  
CMOS input levels from 1.62V to 5.5V.

The MAX14774/MAX14779 feature a 2.5(max) on-  
resistance and an 18m(typ) flatness at +85°C. The  
MAX14774 has a low ±100nA (max) on-leakage current  
at +85°C, while the MAX14779 has ±200nA (max). Each  
switch can carry up to ±200mA (max) of continuous  
current in either direction. The switches maintain the  
performance over the entire common-mode voltage  
range. Both parts are specified for -40°C to +125°C  
industrial temperature range and are available in a 20  
pin (4mm x 4mm) TQFN package.
