MAX4644EUT+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4644EUT+T is a single-pole/double-throw (SPDT) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single supply voltage ranging from +1.8V to +5.5V and features low on-resistance of 4Ω maximum at +5V supply. The device ensures break-before-make switching with turn-on time typically under 20ns. Packaged in a 6-pin SOT23, it offers rail-to-rail analog signal range, low leakage current below 0.35nA, and excellent AC characteristics including -82dB crosstalk at 1MHz. Quiescent power consumption is minimal at approximately 0.01μW.
