Wide bandwidth (500MHz), low on-resistance (12Ω), and
low crosstalk make it suitable for high-frequency and
SOIC-16
other applications. Also this device has exceptionally high
TSSOP-16
current capability which is far greater than most analog
SSOP-16
switches offered today.
The SGM330A offers a high-performance, low-cost
PIN CONFIGURATIONS (TOP VIEW)
solution to switch between video sources. It is specified
-40℃ to +85℃ temperature range. The SGM330A is
SGM330A
available in Green SOIC-16, TSSOP-16 and SSOP-16
packages.

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.

Digital voltage at the IN pin that selects between S1 and S2 analog inputs.
Voltage applied to the D or S1, S2 pins when D or S1, S2 is the switch input.
A voltage that ENABLES the chip.
Capacitance at the digital inputs.
Capacitance at analog I/O (S1, S2, D) with switch OFF.
Capacitance at analog I/O (S1, S2, D) with switch ON.
