_______________General Desc ription
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 broad-
cast-quality video applications. The device is designed
to drive both 50
and 75
cables, and can directly
drive a 75
load to ±3V.
The MAX442 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 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.
