Overview
The ISO6721RBQDRQ1 is an automotive-grade, general-purpose dual-channel digital isolator manufactured by Texas Instruments. It features a reverse pinout configuration within an 8-pin SOIC (D) package. The device supports a supply voltage range of 1.71 V to 5.5 V for both sides and operates over a temperature range of -40°C to +125°C. It utilizes CMOS-logic switching technology for signal transmission.
Feature Summary
- Reverse pinout design facilitates PCB layout flexibility in space-constrained automotive applications.
- Dual-channel architecture provides independent galvanic isolation for two signal paths.
- Automotive qualification ensures reliability under harsh environmental conditions.
Applications
- Automotive body control modules
- Infotainment system interfaces
- Sensor signal isolation
Procurement Notes
Verify the specific suffix 'RFB' or 'RB' against the official datasheet to confirm the reverse pinout variant. Ensure the QDRQ1 designation matches the required automotive grade and packaging format. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a reverse pinout is required for board routing optimization. Confirm that the 50 Mb/s data rate meets the application's timing requirements. Verify that the SOIC-8 package dimensions fit the mechanical constraints of the target enclosure.
Part Context
This device belongs to the ISO6721-Q1 family of automotive digital isolators. It shares core isolation technology with other members but differs in pinout orientation. The family is designed for robust performance in electric vehicle and chassis systems.
Replacement Considerations
ISO6721RFBQDRQ1: Same functional specifications and reverse pinout; verify package compatibility.
FAQ
What is the significance of the reverse pinout?
The reverse pinout allows for easier routing on printed circuit boards by flipping the channel orientation compared to standard layouts.
Does this device support bidirectional communication?
No, the ISO6721RBQDRQ1 is a unidirectional isolator with separate input and output channels.
