MAX4644EUA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4644EUA+ 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 provides a maximum on-resistance of 4Ω at +5V supply. The device features fast switching times with a typical turn-on time of 15ns and turn-off time of 5ns at +5V. It ensures break-before-make operation and maintains low leakage currents across the entire temperature range. Packaged in an 8-pin μMAX format, it is designed for low-power applications.
