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.
