ISO7763DW

Overview

The ISO7763DW is a six-channel digital isolator from Texas Instruments, housed in a 16-pin SOIC package. It features capacitive coupling technology with a data rate of 100 Mb/s and an isolation voltage of 5000 Vrms. The device operates on a supply voltage range of 2.25 V to 5.5 V, drawing a typical operating current of 21 mA. Key electrical parameters include a propagation delay of 11 ns, rise/fall times of 3.9 ns, and a common-mode transient immunity (CMTI) of ±100 kV/µs. It supports bidirectional signal transmission across three forward and three reverse channels.

Feature Summary

• Provides robust electromagnetic compatibility performance with reinforced insulation capabilities
• Features high common-mode transient immunity for reliable operation in noisy environments
• Offers long-term reliability with an expected lifespan exceeding 30 years

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Power metering applications with high-voltage separation needs

Procurement Notes

Verify the specific suffix 'DW' confirms the SOIC-16 package and tape-and-reel or cut-tape availability as per manufacturer specifications. Ensure compliance with RoHS directives and humidity sensitivity levels before procurement. Cross-reference ordering part numbers with official distributor catalogs to confirm exact packaging quantities and moisture barrier bag requirements for storage.

Selection Notes

Select this component when six isolated channels are required within a single compact package. It is suitable for designs demanding high CMTI and reinforced isolation ratings. Consider the 100 Mb/s data rate limit and 5.5 V maximum supply voltage during system architecture planning. Evaluate thermal dissipation requirements given the operating temperature range of -55°C to +125°C.

Part Context

This device belongs to the ISO7763 series of high-speed digital isolators. It utilizes Texas Instruments' silicon dioxide (SiO2) insulation technology for superior EMC performance compared to traditional polymer-based alternatives. The series is designed for applications requiring high reliability and long-term stability in harsh electrical environments.

Replacement Considerations

Direct replacements must match the six-channel configuration, SOIC-16 package, and 5000 Vrms isolation rating. Verify pinout compatibility and electrical characteristics such as data rate and supply voltage range. Consult official substitution guides for equivalent parts within the same family or from other manufacturers offering similar reinforced isolation specs.
