700 MH, 5 A, 4-to-1, Buffered Video Multiplexer

The AD8184 is a high speed 4-to-1 multiplexer. It offers -3 dB signal bandwidth of 700 MHz along with a slew rate of 750 V/µs. With 88 dB of crosstalk and 109 dB isolation, it is useful in many high speed applications. The differential gain and differential phase error of 0.01% and 0.01°, along with 0.1 dB flatness of 75 MHz, make AD8184 ideal for professional video multiplexing. It offers 5 ns switching time, making it an excellent choice for pixel switching (picture-in-picture) while consuming less than 4.4 mA on ±5 V supply voltage.

The AD8184 offers a high speed disable feature allowing the output to be put into a high impedance state. This allows multiple outputs to be connected together for cascading stages while the "OFF" channels do not load the output bus. It operates on voltage supplies of ±5 V and is offered in 14-lead PDIP and SOIC packages.
