19-0137; Rev 1; 3/94 Improved Low-Power, CMOS Analog Switches with Latches _______________General Description ______________________New Features D Maxim’s redesigned DG421/DG423/DG425 monolithic Plug-In Upgrades for Industry-Standard G 4 analog switches now feature guaranteed on-resistance DG421/DG423/DG425 2 matching (3Ω max) between switches and on-resistance Improved r(DS)ON Match Between Channels (3Ω max) flatness over the signal range (4Ω max). These low on- resistance switches (20Ω typ) conduct equally well in both Guaranteed rFLAT(ON) Over Signal Range (4Ω max) 1 Improved Charge Injection (15pC max) / D directions. They guarantee a low charge injection of 15pC maximum and an ESD tolerance of 2000V minimum per Improved Off Leakage Current Over Temperature Method 3015.7. Off leakage current over temperature has (5nA at +85°C) G also been reduced (less than 5nA at +85°C). Withstands Electrostatic Discharge (2000V min) 4 The DG421/DG423/DG425 are precision, dual CMOS per Method 3015.7 2 switches with latchable logic inputs that
