ISO7760FDBQR

Overview

The ISO7760FDBQR is a six-channel digital isolator from Texas Instruments, utilizing capacitive coupling technology. It features a unidirectional 6/0 channel configuration in a 16-SSOP package. Key electrical parameters include a data rate of 100 Mbps, an isolation voltage of 3000 Vrms, and a minimum common-mode transient immunity (CMTI) of 85 kV/µs. The device operates on a supply voltage range of 2.25 V to 5.5 V, with a maximum propagation delay of 16 ns and pulse width distortion of 4.9 ns. It supports an operating temperature range of -55°C to +125°C.

Feature Summary

• Provides reinforced insulation for six independent signal channels using robust capacitive coupling technology.
• Ensures high noise immunity against fast-changing voltage transients with a minimum CMTI rating.
• Supports high-speed data transmission up to 100 Mbps with low propagation delay characteristics.

Applications

• Automotive electronic control units requiring galvanic isolation
• Industrial communication interfaces such as CAN and LIN bus systems
• General-purpose isolated digital signal transmission in noisy environments

Procurement Notes

Verify the specific suffix 'F' indicates general-purpose qualification rather than automotive grade when sourcing. Confirm the 16-SSOP package dimensions match the PCB footprint requirements. Check RoHS compliance status and moisture sensitivity level before assembly planning. Ensure the supplier provides original manufacturer documentation to validate authenticity.

Selection Notes

Select this component when six isolated channels are required in a compact surface-mount package. It is suitable for applications needing moderate isolation voltage and high-speed data rates. Consider the unidirectional nature of the channels during circuit design. Evaluate the thermal performance within the specified wide temperature range for reliability.

Part Context

This part belongs to the ISO776x family of high-speed digital isolators. It shares architectural similarities with other members like the ISO7760QDBQR but differs in qualification level. The family emphasizes robust electromagnetic compatibility and reinforced insulation standards for safety-critical applications.

FAQ

What is the maximum data rate supported by the ISO7760FDBQR?

The device supports a maximum data rate of 100 Mbps across its six channels.
