Overview
The ADG774BRZ-REEL7, produced by Analog Devices Inc., is a monolithic CMOS device that integrates four 2:1 multiplexer/demultiplexers with high impedance outputs. This component is designed to provide low power dissipation while maintaining high switching speed and low on-resistance. The ADG774 is suitable for a wide range of applications due to its extended signal range, which fully extends to the supply rails, and its ability to operate from a single 3 V or 5 V supply.
