ADG841/ADG842 Truth Table Logic (IN) ADG841 ADG842 The ADG841 and ADG842 are low voltage CMOS devices 0 Off On containing a single-pole, single-throw (SPST) switch. The 1 On Off 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 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. Rev. 0 Information furnished by Analog Devices is believed to be accurate and reliable.
