ISO7761QDWQ1

Digital Isolators Overview

The ISO7761QDWQ1 is an automotive-grade digital isolator from Texas Instruments, certified to AEC-Q100 standards. It features six channels with a 5/1 input/output configuration and offers reinforced isolation voltage of 5000 Vrms. The device supports data rates up to 150 Mbps and operates within a temperature range of -40°C to +125°C. Powered by a single supply voltage between 2.25 V and 5.5 V, it utilizes capacitive coupling technology for galvanic isolation. Packaged in a 16-pin SOIC (DW) format, this component ensures high common-mode transient immunity for robust signal transmission in demanding environments.

Digital Isolators Feature Summary

• Automotive qualification ensures reliability under harsh conditions

Digital Isolators Applications

• Automotive data acquisition systems
• Industrial instrumentation interfaces
• Motor control gate drive circuits

Digital Isolators Procurement Notes

Verify the specific suffix 'QDWQ1' matches the required tube packaging and automotive grade designation. Confirm that the 5000 Vrms isolation rating aligns with system safety requirements. Ensure the 16-pin SOIC footprint fits the PCB layout constraints. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Digital Isolators Selection Notes

Select this component when six isolated channels are required in a compact surface-mount package. The 5/1 channel split suits applications needing multiple outputs from a single source. Consider the 150 Mbps speed capability for high-bandwidth communication needs. Evaluate the operating temperature range against the intended environment's extremes.

Digital Isolators Part Context

This part belongs to the ISO776x-Q1 family of automotive digital isolators. It complements other devices like the ISO7741 and ISO7341 by offering higher channel density. The series is designed to replace optocouplers in modern electronic designs, providing superior performance and longevity.
