ISO7341CQDWRQ1

Overview

The ISO7341CQDWRQ1 is an automotive-grade, low-power quad-channel digital isolator from Texas Instruments. It features a 3/1 channel configuration with unidirectional signal paths. The device operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 25 Mb/s. Key electrical specifications include a maximum propagation delay of 31 ns, common-mode transient immunity of 25 kV/µs, and isolation voltage of 3000 Vrms. It functions reliably across a temperature range of -40°C to +125°C and is housed in a 16-pin SOIC package.

Feature Summary

• Provides galvanic isolation for robust EMC performance in automotive environments
• Integrates four independent channels with a 3-forward and 1-reverse configuration
• Ensures high-speed signal integrity with low propagation delay and pulse width distortion

Applications

• Automotive electronic control units (ECUs)
• Inverter gate drive circuits
• Isolated communication interfaces in vehicle networks

Procurement Notes

Verify the specific suffix 'QDWRQ1' to confirm the reel packaging format and tape-and-reel quantity. Ensure the component meets AEC-Q100 qualification requirements for your specific automotive application tier. Cross-reference the manufacturer part number against official Texas Instruments documentation to validate authenticity and revision status before procurement.

Selection Notes

Select this component when a quad-channel isolator with asymmetric channel distribution is required. It is suitable for designs needing low power consumption alongside high common-mode transient immunity. Consider the SOIC-16 package constraints and thermal dissipation capabilities relative to the system's power budget and ambient operating conditions.

Part Context

This device belongs to the ISO7341-Q1 family of automotive digital isolators. It utilizes silicon dioxide (SiO2) insulation technology to provide superior reliability compared to polymer-based alternatives. The series is designed to meet stringent automotive standards for electromagnetic compatibility and long-term operational stability in harsh electrical environments.
