Features

The DG441 and DG442 monolithic CMOS analog switches  
are drop-in replacements for the popular DG201A and  
DG202 series devices. They include four independent single  
pole single throw (SPST) analog switches, TTL and CMOS  
compatible digital inputs, and a voltage reference for logic  
thresholds.

and faster switch time (t  
< 250ns) compared to the

DG201A and DG202. Charge injection has been reduced,  
simplifying sample and hold applications.  
• Single or Split Supply Operation  
The improvements in the DG441 series are made possible by  
using a high voltage silicon-gate process. An epitaxial layer  
prevents the latch-up associated with older CMOS

signals. Power supplies may be single-  
P-P  
The four switches are bilateral, equally matched for AC or  
bidirectional signals. The ON resistance variation with  
analog signals is quite low over a ±5V analog input range.  
The switches in the DG441 and DG442 are identical,  
differing only in the polarity of the selection logic.
