Overview
The ISO7741QDBQRQ1 is an automotive-grade, quad-channel digital isolator from Texas Instruments. It features a 3000Vrms isolation rating and supports data rates up to 100Mbps with a common-mode transient immunity of 85kV/µs. The device operates on a single supply voltage ranging from 2.25V to 5.5V and includes three channels in one direction and one channel in the reverse direction. It utilizes capacitive coupling technology and is housed in a 16-SSOP package with a width of 3.90mm. The component is qualified under AEC-Q100 standards for operation within a temperature range of -40°C to 125°C.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for robust reliability in vehicle environments.
- High-speed signal transmission capability supporting data rates up to 100Mbps with low propagation delay.
- Enhanced electromagnetic compatibility performance characterized by high common-mode transient immunity.
Applications
- Automotive electronic control units requiring galvanic isolation between circuits.
- In-vehicle communication networks utilizing isolated serial interfaces.
- Industrial automation systems demanding reliable signal transmission across noisy environments.
Procurement Notes
Verify the specific suffix QDBQRQ1 to confirm the 16-SSOP package and 3000Vrms isolation rating. Ensure the procurement source provides valid AEC-Q100 certification documentation. Confirm that the delivered components match the automotive grade specifications required for your application. Check for any obsolescence notices or lifecycle status updates from the manufacturer before finalizing orders.
Selection Notes
Select this component when a quad-channel isolator with a 3.90mm wide SSOP footprint is required. It is suitable for designs needing 3000Vrms isolation rather than higher reinforced ratings. Consider the 3:1 channel configuration if asymmetric signal routing is necessary. Evaluate power consumption requirements against the typical current draw per channel at the target operating speed.
Part Context
This part belongs to the ISO774x-Q1 family of automotive digital isolators. It shares functional similarities with other members like the ISO7741QDWRQ1 but differs in packaging and isolation voltage levels. The family is designed to replace optocouplers in automotive applications, offering superior performance in speed, size, and power efficiency while maintaining strict automotive quality standards.
