Description

The D8189 is a high-speed, single-supply, triple 2-to-1 multiplexer in the IC Chips category. It offers a small signal bandwidth of 350 MHz and a large signal bandwidth of 300 MHz, with a slew rate of over 1000 V/μs. The D8189 is well-suited for various high-speed applications, with low levels of hostile crosstalk and off isolation. It has a differential gain and phase error of 0.05% and 0.05° respectively, with a flatness of 0.1 dB up to 70 MHz. This makes it ideal for professional and component video multiplexing. The D8189 has a switching time of 4 ns and consumes less than 20 mA on a single 5 V supply. It also features a high-speed disable feature to set the outputs into a high impedance state, allowing for larger input arrays with minimal off-channel output loading. The D8189 is available in a 24-lead TSSOP package.
