Part details & applications

The MAX4734 is a low on-resistance, low-voltage, 4-channel CMOS analog multiplexer that operates from a single 1.6V to 3.6V supply. This device has fast switching speeds (t_ON = 25ns, t_OFF = 20ns max), handles Rail-to-Rail analog signals, and consumes less than 4µW of quiescent power. The MAX4734 has break-before-make switching.

When powered from a 3V supply, the MAX4734 features low 0.8Ω (max) on-resistance (R_ON), with 0.2Ω (max) R_ON matching and 0.1Ω R_ON flatness. The digital logic input is 1.8V CMOS compatible when using a single 3V supply.

The MAX4734 is available in space-saving 12-pin QFN (3mm x 3mm) and 10-pin µMAX® packages.
