ST3DV520A Description
Doc ID 16885 Rev 4 3/21
1 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.
