0.28 Ω CMOS 1.65 V to 3.6 V Single SPST Switches in SC70 Closed for a Logic 1 Input

The ADG841 and ADG842 are low voltage CMOS devices containing a single-pole, single-throw (SPST) switch. The ADG841 is closed for a Logic 1 input and the ADG842 is open for a Logic 1 input. The devices offer ultralow on resistance of less than 0.48 Ω over the full temperature range. The ADG841 / ADG842 are fully specified for 3.3 V, 2.5 V, and 1.8 V supply operation.

Each switch conducts equally well in both directions when on, and has an input signal range that extends to the supplies. The ADG841 / ADG842 exhibit break-before-make switching action. The ADG841 / ADG842 are available in a 6-lead SC70 package.
