Overview
The ADG774BRQZ, produced by Analog Devices Inc., is a monolithic CMOS device that integrates four 2:1 multiplexer/demultiplexers with high impedance outputs. This device is designed to provide low power dissipation while maintaining high switching speed and low on-resistance. The CMOS process ensures ultralow power consumption, making it ideal for portable and battery-powered instruments. The ADG774BRQZ operates from a single 3 V or 5 V supply and is TTL logic compatible, with a break-before-make switching action.
