• Supports flexible system integration through configurable channel arrangements for various digital interfaces.
• Ensures signal integrity in noisy environments via high common-mode transient immunity capabilities.

Digital Isolators Applications

• Industrial communication protocols such as RS-232, RS-485, and SPI
• Digital input/output isolation for microprocessors and FPGAs
• RTD measurement systems requiring analog-to-digital interface isolation

Digital Isolators Procurement Notes

Verify the specific suffix 'CASE+' corresponds to the standard tube packaging and 150Mbps speed variant. Confirm that the 4/0 channel configuration matches the design requirements, as other variants exist within the MAX14930 family. Ensure compatibility with the intended supply voltage range of 1.71V to 5.5V on both sides of the isolation barrier before finalizing procurement.

Digital Isolators Selection Notes

Select this component when high-speed data transmission up to 150Mbps is required alongside strong noise immunity. It is suitable for applications needing independent power domains on either side of the isolation barrier. Consider the 16-SOIC footprint constraints and ensure the thermal performance meets the operating temperature range of -40°C to +125°C for the specific environment.

Digital Isolators Part Context

This part belongs to the MAX14930 series of general-purpose digital isolators from Analog Devices (Maxim Integrated). The series includes variants with different data rates and channel configurations, all sharing the same core capacitive isolation architecture. These devices are designed to replace traditional optocouplers in modern high-speed digital designs.
