SGM330A Quad, Wide-Bandwidth SPDT Video Analog Switch


The SGM330A is a quad, bidirectional, single-pole/ double-throw (SPDT) CMOS video analog switch (Mux/ DeMux) designed to operate from a single 2.7V to 5.5V power supply. This 2-channel multiplexer/demultiplexer is recommended for both RGB and composite video switching applications. The video switch can be driven from a current output RAMDAC or voltage output composite video source.

Wide bandwidth (500MHz), low on-resistance (12Ω), and low crosstalk make it suitable for high-frequency and other applications. Also this device has exceptionally high current capability which is far greater than most analog switches offered today.

The SGM330A offers a high-performance, low-cost solution to switch between video sources. It is specified -40℃ to +85℃ temperature range. The SGM330A is available in Green SOIC-16, TSSOP-16 and SSOP-16 packages.
