The ST3DV520 supports high definition (HD) analog video switching standards and is also suitable for general purpose switching that requires high signal integrity. The device is designed for very low crosstalk, low bit-to-bit skew and low I/O capacitance. The signal from each input is multiplexed into one of two selected outputs while the unselected switch goes to HI-Z status. ) s ( ct Pin description .# .# )- '.$ O 2/10 !
