The AD8188 （G = 1） and AD8189 （G = 2） are high speed， single-supply， triple 2-to-1 multiplexers. They offer ?3 dB small signal bandwidth of 350 MHz and ?3 dB large signal bandwidth of 300 MHz， along with a slew rate in excess of 1000 V/μs. With ?84 dB of all hostile crosstalk and ?95 dB off isolation， the parts are well suited for many high speed applications. The differential gain and differential phase error of 0.05% and 0.05° respectively， along with 0.1 dB flatness to 70 MHz， make the AD8188 and AD8189 ideal for professional and component video multiplexing. The parts offer 4 ns switching time， making them an excellent choice for switching video signals， while consuming less than 20 mA on a single 5 V supply （100 mW）。 Both devices have a high speed disable feature that sets the outputs into a high impedance state. This allows the building of larger input arrays while minimizing off-channel output loading. The devices are offered in a 24-lead TSSOP.
