MAX4780/MAX4784 19-2365 Rev 4 3/09 0.7 , Low-Voltage, Quad 2:1 Analog Multiplexers General Description Features The MAX4780/MAX4784 are low on-resistance, low- Single-Supply Operation from 1.6V to 4.2V voltage, quad 2:1 analog multiplexers that operate from Low R ON a single +1.6V to +4.2V supply. These devices have 0.7 (+2.7V Supply) fast switching speeds (t = 20ns, t = 8ns), handle ON OFF 2 (+1.8V Supply) rail-to-rail analog signals, and consume less than 1W of quiescent power. 0.1 R Flatness (+2.7V Supply) ON When powered from a +2.7V supply, the MAX4780/ 3mm x 3mm Thin QFN Package MAX4784 feature low 0.7 on-resistance (R ), and ON 0.1 R flatness. The digital logic input is +1.8V +1.8V CMOS Logic Compatible ON CMOS-logic compatible when using a single +3V supply. Fast Switching: t = 20ns, t = 8ns ON OFF The MAX4780/MAX4784 are available in 16-pin TSSOP and 3mm x 3mm thin QFN packages.

Limit forward current to maximum current rating. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
