MAX442

19-0016; Rev 1; 1/95 140MHz, 2-Channel Video Multiplexer/Amplifier _______________General Description The MAX442 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 broadcast-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 video amplifier is compensated for unitygain stability, and features a 140MHz bandwidth and a 250V/µs slew rate. The multiplexer’s low input capacitance (4pF with the channel on or off) maximizes highspeed performance, and a ground pin separating the two input channels minimizes crosstalk and simplifies board layout. The MAX442 operates from ±5V supplies and typically consumes 300mW. For applications that require more input channels, see the data sheets for the MAX440 8channel mux/amp and the MAX441 4-channel mux/amp. ____________________________Features o 140MHz Unity-Gain Bandwidth o 250V/µs Slew Rate o 0.07%/0.09° Differential Gain/Phase Error o 36ns Channel Switch Time o No External Compensation Components o 8-Pin DIP and SO Packages o Directly Drives 50Ω and 75Ω Cables MAX442 ______________Ordering Information PART MAX442CPA MAX442CSA MAX442C/D MAX442EPA MAX442ESA TEMP.
