SGM330A
Quad, Wide-Bandwidth
SPDT Video Analog Switch
GENERAL DESCRIPTION
The SGM330A is a quad, bidirectional, single-pole/
double-throw (SPDT) CMOS video analog switch
(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 (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.

NOTE:
Stresses beyond those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device. These
are stress ratings only, and functional operation of the device at
these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended
periods may affect device reliability.
CAUTION
This integrated circuit can be damaged by ESD if you don’t pay
attention to ESD protection. SGMICRO 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.
SGMICRO reserves the right to make any change in circuit
design, specification or other related things if necessary without
notice at any time. Please contact SGMICRO sales office to get
the latest datasheet.
