The MAX442_1281508 combines a 140MHz video amplifier with a high-speed, 2-channel multiplexer in an 8-pin package.With its 36ns switching time and low differential gain (0.07%) and phase (0.09°) errors, it is ideal for broad-cast-quality video applications.  The device is designed to drive both 50Ω and 75Ω cables, and can directly drive a 75Ω load to ±3V.

The MAX442_1281508 video amplifier is compensated for unity-gain stability, and features a 140MHz bandwidth and a 250V/µs slew rate.  The multiplexer's low input capaci-tance (4pF with the channel on or off) maximizes high-speed performance, and a ground pin separating the  two input channels minimizes crosstalk and simplifies board layout.

The MAX442_1281508 operates from ±5V supplies and typically consumes 300mW.  For applications that require more input channels, see the data sheets for the MAX440 8-channel mux/amp and the MAX441 4-channel mux/amp.
