Q: How does the CH443K handle level translation?

The SEL pin is driven by an external microcontroller, and the COM pin output voltage is determined by the voltages applied to the CH0 and CH1 pins, allowing for flexible level shifting.

Q: What should sourcing teams check before buying CH443K?

Check lifecycle (Active), compliance data, distributor availability, and approved-source coverage. Current sourcing signal: Low; readiness: easy.

Q: What is the pinout of CH443K?

Use the CH443K datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about CH443K pinout to locate pins, power rails, and interface signals before layout.

Question 1

What is the CH443K?

Accepted Answer

The CH443K is a single-pole double-throw (SPDT) analog switch chip from WCH, designed for 5V systems but capable of operating down to 1.8V.

Question 2

What are the primary applications of the CH443K?

Accepted Answer

It is primarily used for video and USB signal switching, implementing simple logic gate functions (like AND/OR/NOT), and performing digital signal level translation.

Question 3

What are the key electrical characteristics?

Accepted Answer

It features a low typical on-resistance of 5Ω, fast switching times (Ton/Toff < 5ns), and high bandwidth (up to 550MHz), making it suitable for high-speed signal paths.

Question 4
