The AD8183 and AD8185 are high-speed triple 2:1 multiplexers with features including fully buffered inputs and outputs, fast channel switching, high-speed bandwidth, low power consumption, and excellent video specifications.
The AD8183 (gain = +1) and AD8185 (gain = +2) are high‑speed triple 2:1 multiplexers designed for professional video and RGB applications. They provide up to 380 MHz -3 dB bandwidth for small‑signal inputs and feature a fast 15 ns channel‑to‑channel switching time while consuming less than 25 mA from a +5 V supply.
Both devices include a high‑impedance disable feature for building larger input arrays, operate from a 4.5 V to 5.5 V supply, and are supplied in a 24‑lead TSSOP package. The datasheet details electrical performance, absolute maximum ratings, and recommended operating conditions.
