ADG794 is a low-power, 300MHz quad 2:1 switch, supporting HDTV audio/video switching.
The ADG794 is a monolithic CMOS quad 2:1 multiplexor/demultiplexer with high‑impedance outputs, low insertion loss, and a typical bandwidth of 300 MHz. It operates from a single 3.3 V or 5 V supply and is TTL/CMOS compatible, making it suitable for HDTV, DVD‑R, and audio/video switching applications.
The document includes functional block diagrams, pin configuration tables, absolute maximum ratings, ESD protection information, typical performance graphs, outline dimensions, and an ordering guide for the 16‑lead QSOP package.
