Analog Devices AD8183/AD8185 Datasheet
The AD8183 (G = +1) and AD8185 (G = +2) are high‑speed triple 2:1 multiplexers offering up to 380 MHz –3 dB bandwidth, 1000 V/µs slew rate and 15 ns channel‑to‑channel switching. They feature low crosstalk (‑84 dB @ 5 MHz) and high OFF isolation (‑100 dB @ 10 MHz), making them suitable for professional video, RGB switching, and picture‑in‑picture applications.
Both devices operate from a +5 V supply, consume less than 25 mA, and are available in a 24‑lead plastic TSSOP (RU‑24) package. The datasheet includes detailed electrical specifications, absolute maximum ratings, pin configuration, and layout dimensions.
