The AD8184 is a high speed 4-to-1 multiplexer with a -3 dB signal bandwidth of 700 MHz and a slew rate of 750 V/µs. It offers 95 dB of crosstalk and 115 dB isolation, making it useful in many high speed applications. With a differential gain and differential phase error of 0.01% and 0.01°, and a flatness of 0.1 dB up to 75 MHz, the AD8184 is ideal for professional video multiplexing. It has a switching time of 10 ns, making it an excellent choice for pixel switching (picture-in-picture), while consuming less than 4.5 mA on ±5 V supply voltage. The AD8184 has a high speed disable feature that allows the output to be put into a high impedance state, enabling multiple outputs to be connected together for cascading stages without loading the output bus. It operates on ±5 V voltage supplies and is available in 14-lead PDIP and SOIC packages.
The AD8184 video multiplexer provides a high‑speed 4‑to‑1 switching solution for professional video applications. It offers a –3 dB bandwidth of 700 MHz, a slew rate of 750 V/µs, and a channel‑to‑channel switching time of 10 ns, while consuming less than 4.5 mA from a ±5 V supply. The device includes a fast disable feature that places the output in a high‑impedance state, allowing multiple muxes to be cascaded.
The part is supplied in 14‑lead PDIP and SOIC packages and includes specifications such as –95 dB crosstalk, –115 dB OFF isolation, and low power dissipation. Layout guidelines emphasize short signal traces, proper grounding, and the use of surface‑mount bypass capacitors to maintain performance at high frequencies.
