♦ 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
