ISO7763FQDBQQ1

Overview

The ISO7763FQDBQQ1 is an automotive-grade digital isolator from the ISO776x-Q1 series, manufactured by Texas Instruments. It features six channels with a 3/3 input/output configuration and utilizes capacitive coupling technology. The device supports data rates up to 100 Mbps and offers a minimum common-mode transient immunity of 85 kV/µs. It operates within a supply voltage range of 2.25 V to 5.5 V and is qualified under AEC-Q100 standards for automotive applications. The component is housed in a 16-SSOP package.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for robust performance in vehicle environments
• High-speed signal transmission capability supporting data rates up to 100 Mbps
• Enhanced noise immunity with a minimum common-mode transient immunity of 85 kV/µs
• Six-channel isolation architecture providing flexible bidirectional or unidirectional signal paths

Applications

• Controller Area Network (CAN) bus isolation in automotive systems
• Isolation between microcontrollers and peripheral devices in electric vehicles
• Signal isolation in automotive sensor interfaces and gate driver circuits

Procurement Notes

Verify the specific suffix 'QQ1' indicates tube packaging rather than tape-and-reel configurations found in other variants like 'QRQ1'. Confirm that the 'F' designation aligns with required functional specifications for your design. Ensure compatibility with AEC-Q100 grade requirements for your target automotive application segment before finalizing procurement orders.

Selection Notes

Select this component when a six-channel isolator with a symmetric 3-input/3-output configuration is required for automotive CAN networks. It is suitable for designs needing high common-mode transient immunity and operation across extended temperature ranges. Consider alternative channel counts if fewer isolation points are sufficient for the specific circuit topology.

Part Context

This part belongs to the ISO776x-Q1 family of automotive digital isolators. It shares the same core capacitive coupling technology and SSOP-16 footprint as related models such as the ISO7762QDBQQ1 and ISO7761FQDBQQ1. The primary distinction lies in the channel configuration, with this model offering a balanced 3/3 split compared to asymmetric alternatives.

Replacement Considerations

Direct substitutes include ISO7763FQDBQRQ1 for identical functionality in tape-and-reel packaging. For different channel configurations, consider ISO7762QDBQQ1 (4/2) or ISO7761FQDBQQ1 (5/1). Verify pinout compatibility and thermal characteristics when swapping between these family members.
