MAX14885EETL+

Product Summary

The MAX14885EETL+ is a low-capacitance VGA 2:2 dual-graphics crossover switch, which integrates high-bandwidth analog switches, level-translating buffers, and level-translating FET switches. The MAX14885EETL+ implements a complete 2:2 dual-graphics crossover solution for VGA signal switching. The MAX14885EETL+ provides 12 very high-frequency 700MHz (typ) SPST switches for RGB signals, four lowfrequency clamping switches for display data channel (DDC) signals, two pairs of level-translating buffers for the HSYNC and VSYNC signals, and integrated extended ESD protection. The MAX14885EETL+ is used to select one of two sources to either of two destinations within a laptop computer.
