AD8188/AD8189 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.
The AD8188 (G = 1) and AD8189 (G = 2) are high‑speed, single‑supply, triple 2‑to‑1 multiplexers offering a −3 dB small‑signal bandwidth of 350 MHz and a large‑signal bandwidth of 300 MHz. They feature 4 ns switching, 1000 V/µs slew rate, low current draw (~19 mA) and excellent video specifications such as low differential gain error (0.05 %) and low crosstalk.
These devices are suited for high‑speed video applications like RGB switching in LCD and plasma displays. An evaluation board is provided for single‑supply operation, with AC‑coupled inputs, termination resistors and a VREF adjustment potentiometer for the AD8189. The datasheet includes detailed specifications, pin descriptions, typical performance curves, and ordering information.

They operate from a single 5 V supply and draw about 19 mA of quiescent current per channel.
A high‑impedance disable feature sets the outputs to a high‑Z state, allowing larger input arrays with minimal loading.
