ISO7140FCCDBQR

Overview

The ISO7140FCCDBQR is a small-footprint, low-power quad-channel digital isolator from Texas Instruments. It features four forward channels with no reverse channels, operating at data rates up to 50 Mb/s. The device provides 2500 Vrms isolation via capacitive coupling and supports supply voltages between 2.7 V and 5 V. It exhibits a propagation delay of 23 ns and operates within a temperature range of -40°C to +125°C. Packaged in an SSOP-16, it includes noise filtering for robust performance.

Feature Summary

• Small-footprint design suitable for space-constrained applications
• Low-power consumption optimized for energy efficiency
• Integrated noise filter for enhanced signal integrity
• Capacitive coupling technology for reliable isolation

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing high-reliability signal transmission
• Power electronics control circuits
• Communication interfaces in noisy environments

Procurement Notes

Verify the specific suffix 'DBQR' indicates the reel packaging format distinct from tube variants like 'DBQ'. Confirm RoHS compliance status through official documentation before procurement. Ensure compatibility with standard SSOP-16 footprints during PCB layout. Check for moisture sensitivity level requirements if storage conditions are not controlled.

Selection Notes

Select this component when four unidirectional isolated channels are required within a compact package. Consider the 50 Mb/s data rate limit for signal speed requirements. Evaluate power budget constraints against the specified operating current. Verify that the 2500 Vrms isolation rating meets system safety standards.

Part Context

This part belongs to the ISO7140 family of digital isolators designed for general-purpose applications. It shares architectural similarities with other members but differs in channel configuration and packaging options. The series emphasizes low power and small size compared to older isolation technologies.

Replacement Considerations

ISO7140FCCDBQ serves as a tube-packaged alternative with identical electrical characteristics. ISO7141CCDBQR offers a different channel split (3/1) within the same package. Verify pinout compatibility and insulation ratings when substituting.
