The CXAS42254 integrates high-bandwidth analog switches, level-shifting buffers and level-translating FET switches. The device implements a complete 2:2 dual-graphics crossover solution for VGA signal switching. The CXAS42254 provides 12 very high-frequency 700MHz SPST switches for RGB signals, 4 low- frequency clamping switches for the Display Data Channel(DDC) signals, 2 pairs of level-shifting buffers for the HSYNC and VSYNC signals, and also integrated extended ESD protection. The CXAS42254 is used to select one of two sources to either of two destinations within a laptop computer. Horizontal and vertical synchronization (SH_/SV_) inputs feature level-shifting buffers to support lowvoltage controllers and standard 5V TTL-level monitors. DDC, consisting of SDA_ and SCL_, are FET switches that protect the low-voltage VGA source from potential damage from high-voltage presence on the monitor while reducing capacitive load. All 14 output terminals of the CXAS42254feature high-ESD protection to ±15kV Human Body Model (HBM) and ±6kV IEC 61000-4-2 Contact. All other pins are protected to ±2kV HBM. The CXAS42254 is available in the TQFN5X5-40 package with exposed pad.
