_______________General Description
The MAX4141 is a wideband 330MHz, 700V/µs 4x1 multiplexer optimized for high-definition, broadcast­quality, 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 high­impedance state and reduces the operating current to only 250µA. The open-loop architecture allows the out­put 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
