DG423
Description
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 onresistance switches (20Ω typ) conduct equally well in both directions. They guarantee a low charge injection of 15p C maximum and an ESD tolerance of 2000V minimum per Method 3015.7. Off leakage current over temperature has also been reduced (less than 5n A at +85°C). The DG421/DG423/DG425 are precision, dual CMOS switches with latchable logic inputs that simplify interfacing with microprocessors (µPs). The single-pole/singlethrow DG421 and double-pole/single-throw DG425 are normally open dual switches. The dual, singlepole/double-throw DG423 has two normally open and two normally closed switches. Fast switching times (175ns for t ON and 145ns for t OFF ) and low power consumption (35µW max) make these parts ideal for battery-powered applications requiring µP-patible...
