330MHz, 4x1 Precision Video Multiplexer
_______________General Description
The MAX4141 is a wideband 330MHz, 700V/µs 4x1
multiplexer optimized for high-definition, broadcast-
quality, composite (HDTV, NTSC, PAL, SECAM) video
switching arrays. The device includes four open-loop
buffer amplifiers with a 0.1dB gain flatness of 150MHz,
and enable and switch-control logic. The MAX4141
operates from ±5V supplies and features differential
phase and gain error of only 0.01°/0.01%. The ultra-low
switching glitch (less than 13mV) is positive to avoid
confusion with any sync pulses.
Ideal as a building block for large switch arrays, the
MAX4141 features a constant, high input impedance
and a disable function that puts the output into a high-
impedance state and reduces the operating current to
only 250µA. The open-loop architecture allows the out-
put to drive capacitive loads without oscillation.
Other key features include -66dB crosstalk (30MHz),
-74dB isolation (30MHz), less than 10mV offset voltage,
and a 110MHz full-power bandwidth (1.4Vp-p). The
MAX4141 is available in a 14-pin narrow SO package.
