TD541S-44H5

Digital Isolators Overview

The TD541S-44H5 is a digital isolator manufactured by Mornsun America, LLC. It features four channels with a 5000VDC isolation voltage and supports SPI interfaces at data rates up to 150Mbps. The device utilizes capacitive coupling technology and includes an integrated isolated power supply. Key electrical specifications include a minimum common-mode transient immunity (CMTI) of 75kV/µs, maximum propagation delays of 13ns, and pulse width distortion of 4.5ns. It operates on a 4.75V to 5.25V supply within a temperature range of -40°C to 125°C.

Digital Isolators Feature Summary

• Integrates a high-voltage isolated power supply for single-supply operation
• Provides robust signal transmission via capacitive coupling technology
• Ensures high noise immunity through significant common-mode transient rejection capabilities

Digital Isolators Applications

• Industrial communication systems requiring galvanic isolation
• Motor control applications involving high-voltage switching
• Medical equipment needing reliable signal separation

Digital Isolators Procurement Notes

Verify the component status as not recommended for new designs before procurement. Confirm that the 16-BDFN package dimensions match the target PCB layout. Ensure the supplier provides official datasheets to validate the specific H5 suffix characteristics against project requirements.

Digital Isolators Selection Notes

Select this component when a self-contained isolated power solution is required to simplify circuit design. The four-channel configuration supports complex multi-line protocols like SPI. Verify that the 150Mbps speed meets system timing constraints and that the 5000VDC isolation rating satisfies safety standards.
