ISO7763DBQR

Overview

The ISO7763DBQR is a high-speed, robust EMC reinforced six-channel digital isolator manufactured by Texas Instruments. It features capacitive coupling technology within an SSOP-16 package. The device supports a data rate of 100 Mb/s with a propagation delay of 11 ns and rise/fall times of 3.9 ns. It operates on a supply voltage range of 2.25 V to 5.5 V, consuming 25.7 mA of operating current. The insulation voltage is rated at 3000 Vrms, and it functions within a temperature range of -55°C to +125°C.

Feature Summary

• Provides reinforced isolation for six independent channels using capacitive coupling technology.
• Ensures signal integrity in electrically noisy environments through robust electromagnetic compatibility design.
• Supports bidirectional and unidirectional data transmission across three forward and three reverse channels.

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 'DBQR' corresponds to the SSOP-16 reel packaging configuration. Confirm that the required insulation voltage rating of 3000 Vrms meets the safety standards for your application. Ensure the operating temperature range covers your environmental conditions. Check for RoHS compliance status if restricted substances are a concern.

Selection Notes

Select this component when six isolated channels are necessary within a single package. Consider the 100 Mb/s data rate for moderate-speed communication links. Evaluate the 25.7 mA power consumption against system energy constraints. Compare the 3000 Vrms insulation rating against higher-rated alternatives if increased safety margins are required.

Part Context

This part belongs to the ISO776x family of high-speed digital isolators from Texas Instruments. It shares the SSOP-16 footprint with other variants like the ISO7762 but differs in channel count and directionality. The series is designed for applications demanding both high speed and strong electromagnetic interference immunity.

Replacement Considerations

Check for direct pin-compatible substitutes within the ISO776x family, such as the ISO7762DBQR, which offers a 4/2 channel configuration. Verify that any replacement maintains the same 3000 Vrms insulation rating and SSOP-16 package dimensions.
