Overview
The ADG774BR, produced by Analog Devices Inc., is a monolithic CMOS device that integrates four 2:1 multiplexer/demultiplexers with high impedance outputs. This quad SPDT switch is designed for high-performance applications, offering low power dissipation, high switching speed, and low on resistance. The device operates from a single 3 V to 5 V supply and is compatible with TTL and CMOS logic. It is particularly suited for applications requiring wide bandwidth, low distortion, and fast switching times.
