• Provides independent data channels allowing flexible input/output configurations across the isolation barrier.
• Ensures DC correctness without requiring optical components, eliminating light-emitting diode degradation issues.

Digital Isolators Applications

• Industrial fieldbus communication interfaces
• SPI bus isolation in sensor networks
• Programmable logic controller (PLC) I/O modules
• Power metering and energy monitoring systems

Digital Isolators Procurement Notes

Verify the specific suffix 'RL7' against the base part number when sourcing reels versus tubes. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference pinout diagrams with target PCB layout requirements to prevent orientation errors during assembly.

Digital Isolators Selection Notes

Select this component for applications requiring high-density six-channel isolation in standard surface-mount packages. The 5/1 configuration suits designs needing multiple inputs and single outputs or vice versa. Consider the 13 ns propagation delay for timing-critical synchronous buses. Evaluate power consumption at 1.7 V to 5.5 V ranges for low-voltage system compatibility.

Digital Isolators Part Context

This device belongs to the ADuM16xN family of six-channel digital isolators designed for SPI and general-purpose interface applications. It serves as a direct replacement for traditional optocouplers in space-constrained environments. The family shares core magnetic coupling architecture while varying channel counts and configurations to meet diverse interface needs.

Digital Isolators Replacement Considerations

ADUM162N0BRZ provides a 4/2 channel configuration. ADUM163N1BRZ offers a 3/3 channel split. Both share identical electrical specifications and package dimensions. Verify channel directionality matches circuit topology before substitution.
