Overview
The ADG774BRQZ-REEL7 is a quad 2:1 analog multiplexer/demultiplexer manufactured by Analog Devices. This monolithic CMOS device is designed to operate from a single 3 V or 5 V supply, making it versatile for various applications. The ADG774BRQZ-REEL7 features high impedance outputs and conducts equally well in both directions when ON, with an input signal range that extends to the supply rails. It is particularly suited for applications requiring low power dissipation, high switching speed, and low on resistance.
