ISO7762FDBQ

Overview

The ISO7762FDBQ is a high-performance, six-channel digital isolator from Texas Instruments housed in a 16-SSOP package. It features four forward and two reverse channels with a data rate of 100 Mb/s. The device offers a reinforced isolation rating of 3000 Vrms per UL 1577 standards. Operating voltage ranges from 2.25 V to 5.5 V, with a typical supply current of 25.7 mA. Propagation delay is 11 ns, and rise/fall times are 3.9 ns. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides robust electromagnetic compatibility (EMC) performance for noisy industrial environments.
• Offers reinforced insulation capabilities meeting UL 1577 safety standards.
• Integrates six independent channels in a compact surface-mount package.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Power metering applications

Procurement Notes

Verify the specific suffix 'F' indicates tape-and-reel packaging configuration when ordering. Confirm that the DBQ package variant meets the required 3000 Vrms isolation rating rather than the higher DW package rating. Ensure the design supports the specified 2.25 V to 5.5 V supply range and thermal requirements for the SSOP-16 footprint.

Selection Notes

Select this component when a six-channel isolator with reinforced safety ratings is required. The DBQ package provides 3000 Vrms isolation, suitable for many industrial applications. Consider the ISO7762DW variant if 5000 Vrms isolation is necessary. Verify channel configuration needs against the 4/2 split provided by this model.

Part Context

This part belongs to the ISO776x family of high-speed digital isolators. These devices utilize capacitive coupling technology to transmit digital signals across isolation barriers. The family includes variants with different isolation ratings and package options to support diverse system design constraints.

Replacement Considerations

Direct replacements include other ISO7762 variants such as ISO7762DBQR or ISO7762QDBQRQ1, depending on packaging and automotive qualification requirements. Ensure substitute parts match the 16-SSOP footprint and 3000 Vrms isolation rating.
