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 above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification 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 last datasheet.
