GENERAL DESCRIPTION
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.
