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.
DescriptionThe MAX4111/MAX4121/MAX4221 wideband video switches are optimized for high-definition, broadcastquality,composite (HDTV, NTSC, PAL, SECAM, and RGB) video switching arrays. Their open-loop buffer amplifiers offer 0.1dB gain flatness to 150MHz. They operate from ±5V supplies and feature differential phase and gain error of only 0.01°/0.01%, respectively.The ultra-low switching glitch (13mV) is positive to avoid confusion with any sync pulse.
Ideal as building blocks in large arrays, MAX4111 feature a constant, high input impedance and a disable function that puts the outputs into a high-impedance state and reduces the operating current to only 250A.The open-loop architecture allows the outputs to drive capacitive loads without oscillation. Other key features include -92dB crosstalk and -78dB isolation (MAX4121).
The MAX4111/MAX4121/MAX4221 are offered in narrow plastic DIP and SO packages. See the table below for key features:
