SGM330A
GENERAL DESCRIPTION
The SGM330A is a Quad, bidirectional, single-pole/double-
throw (SPDT) CMOS Video analog switches (Mux/DeMux)
designed to operate at a single
+
5V 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 (6Ω) , 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°C to
+85°C temperature range. The
SGM330A
has lead (Pb)

Magnitude variation between analog input and output pins when the switch is ON and the dc
offset of composite-video signal varies at the analog input pin. In the NTSC standard, the
frequency of the video signal is 3.58 MHz, and dc offset is from 0 to 0.714 V.
Phase variation between analog input and output pins when the switch is ON and the dc offset
of composite-video signal varies at the analog input pin. In the NTSC standard, the frequency

CAUTION
This integrated circuit can be damaged by ESD if you don’t pay attention to ESD protection. Shengbang Micro-electronics
recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and
installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
