The ADG1311/ADG1312/ADG1313 are monolithic CMOS devices containing four independently selectable switches designed on a CMOS process. The ADG1311/ADG1312/ADG1313 contain four independent single-pole/single-throw (SPST) switches. The ADG1311 and ADG1312 differ only in that the digital control logic is inverted. The ADG1311 switches are turned on with Logic 0 on the appro-priate control input, while Logic 1 is required for the ADG1312. The ADG1313 has two switches with digital control logic similar to the ADG1311; the logic is inverted on the other two switches. The ADG1313 exhibits break-before-make switching action for use in multiplexer applications.
