Description

The ST3DV520A 20- to 10-bit multiplexer/demultiplexer is a high bandwidth bidirectional switch with low RON suitable for analog video applications.

The signal from each input is multiplexed into one of two selected outputs, while the unselected switch goes into Hi-Z status. The device is designed for very low crosstalk, low bit-to-bit skew and low I/O capacitance.

The ST3DV520A supports high definition (HD) video switching standards and is also suitable for general-purpose switching that requires high signal integrity.
