General Description

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.
