The AD8188 (G = 1) and AD8189 (G = 2) are high speed, single-supply, triple 2-to-1 multiplexers. -3dB small signal bandwidth of 350MHz and -3dB large signal bandwidth of 300MHz, along with a slew rate in excess of 1000V/micro second. With -84dB of all hostile crosstalk and -95dB 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 0.1dB flatness to 70MHz, make the AD8188 and AD8189 ideal for professional and component video multiplexing. The parts offer 4ns switching time, making them an excellent choice for switching video signals, while consuming less than 20mA on a single 5V supply (100mW). 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.
