19-2365; Rev 3; 12/04 0.7Ω, Low-Voltage, Quad 2:1 Analog Multiplexers General Description www.datasheet4u.com Features ♦ Single-Supply Operation from 1.6V to 4.2V ♦ Low RON 0.7Ω (+2.7V Supply) 2Ω (+1.8V Supply) ♦ 0.1Ω RON Flatness (+2.7V Supply) ♦ 3mm x 3mm Thin QFN Package ♦ +1.8V CMOS Logic Compatible ♦ Fast Switching: tON = 20ns, tOFF = 8ns MAX4780/MAX4784 The MAX4780/MAX4784 are low on-resistance, lowvoltage, quad 2:1 analog multiplexers that operate from a single +1.6V to +4.2V supply. These devices have fast switching speeds (tON = 20ns, tOFF = 8ns), handle rail-to-rail analog signals, and consume less than 1µW of quiescent power. When powered from a +2.7V supply, the MAX4780/ MAX4784 feature low 0.7Ω on-resistance (RON), and 0.1 Ω R ON flatness. The digital logic input is +1.8V CMOS-logic compatible when using a single +3V supply. 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.
