NCS6433DR2G

Analog Switches - Special Purpose Overview

The NCS6433DR2G is a wideband, bidirectional, quad 2:1 NMOS-based video switch manufactured by onsemi. It supports RGB, composite, S-Video, and component video signals with a typical bandwidth of 570 MHz. The device features low crosstalk (-80 dB at 10 MHz), low on-resistance (4 Ω typical), and fast switching times under 10 ns. It operates on a single 5 V supply with a maximum quiescent current of 3 µA. Control inputs are TTL/CMOS compatible, and the unit includes ESD HBM protection rated at 8 kV.

Analog Switches - Special Purpose Procurement Notes

Verify the specific package suffix to ensure correct physical dimensions. The DR2G designation indicates an SOIC-16 package supplied in tape and reel format. Confirm that the ordering quantity aligns with standard reel specifications provided by the manufacturer. Ensure compatibility with existing PCB footprints before finalizing procurement orders.

Analog Switches - Special Purpose Selection Notes

Select this component when high-frequency signal integrity is required for video routing. The wide bandwidth ensures minimal signal degradation across various video formats. Consider the low power consumption for battery-operated or thermally constrained designs. Verify that the operating voltage range matches the system's 5 V logic levels.

Analog Switches - Special Purpose Part Context

This part belongs to the NCS6433 family of video switches designed for consumer electronics. It serves as a multiplexer/demultiplexer solution for routing multiple video sources to a single display. The device integrates flow control capabilities to manage signal paths efficiently in complex display architectures.

Analog Switches - Special Purpose Replacement Considerations

The NCS6433DTBR2G is a pin-compatible alternative available in a TSSOP-16 package. Both variants share identical electrical characteristics and functionality. Select the DTBR2G variant if a thinner profile or different mounting style is required for the application design.

Analog Switches - Special Purpose FAQ

What is the maximum operating voltage for the NCS6433?

The recommended operating supply voltage is 5 V, with a maximum rating of 5.5 V.

How does the SEL input affect the data path?

The SEL input controls the multiplexer/demultiplexer path. When SEL is low, A connects to B1; when SEL is high, A connects to B2.

Is the NCS6433 capable of handling digital video signals?

Yes, it is suitable for RGB, composite, S-Video, and component video (YPbPr) signals.
