SGM330A
GENERAL DESCRIPTION
The SGM330A is a Quad, bidirectional, single-pole/doublethrow (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 (6) , 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 -40C to +85C temperature range. The SGM330A has lead (Pb)

The peak analog voltage is 0.714V Propagation delay measured between 50% of the digital input to 90% of the analog output when switch is turned OFF. The peak analog voltage is 0.714V response of the switch in the ON state measured at 3dB down Is an unwanted signal coupled from channel to channel. Measured in -dB. XTALK = 20 LOG VOUT/VIN. This is non-adjacent crosstalk 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 of the video signal is 3.58 MHz, and dc offset is from 0 to 0.714 V. Off isolation is the resistance (measured in -dB) between the input and output with the switch off (NO)

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.
