Description

ST3DV520

The ST3DV520 is a 16- to 8-bit bidirectional multiplexer/demultiplexer low RON and high

bandwidth switch suitable for analog video applications.

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.
