350 MH Single-Supply (5 V) Triple 2:1 Multiplexer

The AD8189 (G = 2) is a high speed, single-supply, triple 2-to-1 multiplexer. It offers -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 part is 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 ideal for professional and component video multiplexing. The part offers 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). The device has 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 device is offered in a 24-lead TSSOP.
