Audio signal routing Video signal routing The ADG1211/ADG1212/ADG1213 contain four independent Communication systems

single-pole/single-throw (SPST) switches. The ADG1211 and ADG1212 differ only in that the digital control logic is inverted.

GENERAL DESCRIPTION

The ADG1211 switches are turned on with Logic 0 on the The ADG1211/ADG1212/ADG1213 are monolithic complemen- appropriate control input, while Logic 1 is required for the tary metal-oxide semiconductor (CMOS) devices containing ADG1212. The ADG1213 has two switches with digital control four independently selectable switches designed on an i CMOS logic similar to that of the ADG1211; the logic is inverted on (industrial CMOS) process. i CMOS is a modular manufacturing the other two switches. The ADG1213 exhibits break-before- process combining high voltage CMOS and bipolar technologies. make switching action for use in multiplexer applications.
