The ADG794 is a low-voltage, 300 MHz quad 2:1 multiplexer/demultiplexer with high impedance outputs. The CMOS process provides low power dissipation yet gives high switching speed and low insertion loss. The ADG794 is suitable for RGB switches, HDTV, DVD-R and audio/video switches.
The ADG794 is a monolithic CMOS device that integrates four 2:1 multiplexers/demultiplexers with high‑impedance outputs. It operates from a single 3.3 V or 5 V supply, offers a wide 300 MHz bandwidth, low insertion loss (5 Ω typical on‑resistance), and ultra‑low quiescent current (1 nA typical). The device is TTL/CMOS compatible and includes robust ESD protection.
The datasheet provides detailed specifications, pin configurations, absolute maximum ratings, typical performance curves, and application examples such as RGB video switching and audio/video routing. Ordering information and outline dimensions for the 16‑lead QSOP package are also included.
