♦ Plug-In Upgrades for Industry-Standard  
DG421/DG423/DG425  
Maxim’s redesigned DG421/DG423/DG425 monolithic  
analog switches now feature guaranteed on-resistance  
matching (3Ω max) between switches and on-resistance  
flatness over the signal range (4Ω max). These low on-  
resistance switches (20Ω typ) conduct equally well in both  
directions. They guarantee a low charge injection of 15pC  
maximum and an ESD tolerance of 2000V minimum per  
Method 3015.7. Off leakage current over temperature has  
also been reduced (less than 5nA at +85°C).

The DG421/DG423/DG425 are precision, dual CMOS  
switches with latchable logic inputs that simplify inter-  
facing with microprocessors (µPs). The single-pole/single-  
throw DG421 and double-pole/single-throw DG425 are  
norma lly op e n d ua l s witc he s . The d ua l, s ing le -  
pole/double-throw DG423 has two normally open and  
two normally closed switches. Fast switching times
