GENERAL DESCRIPTION
The ADG1221/ADG1222/ADG1223 are monolithic, complemen- ADG1222. The ADG1223 has one switch with digital control tary metal-oxide semiconductor (CMOS) devices containing logic similar to that of the ADG1221; the logic is inverted on four independently selectable switches designed on an iCMOS the other switch. The ADG1223 exhibits break-before-make (industrial CMOS) process. iCMOS is a modular manufacturing switching action for use in multiplexer applications. Each process combining high voltage CMOS and bipolar technologies. switch conducts equally well in both directions when on and It enables the development of a wide range of high performance has an input signal range that extends to the supplies. In the off analog ICs, capable of 33 V operation, in a footprint that no condition, signal levels up to the supplies are blocked. previous generation of high voltage parts has been able to achieve.
