The MAX4780/MAX4784 are low on-resistance, low-voltage, 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 0.1Ω RON 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.
The MAX4780 and MAX4784 are low‑on‑resistance, low‑voltage quad 2:1 analog multiplexers that operate from a single +1.6 V to +4.2 V supply. They feature fast switching (tON = 20 ns, tOFF = 8 ns), rail‑to‑rail analog signal handling, and a quiescent power consumption of less than 1 µW.
Available in 16‑pin TSSOP and 3 mm × 3 mm thin QFN packages, the devices accept +1.8 V CMOS logic inputs and are suited for power‑routing, battery‑powered systems, audio/video signal routing, low‑voltage data‑acquisition, and communications circuits.
