ISO7141FCCDBQ

Digital Isolators Overview

The ISO7141FCCDBQ is a general-purpose digital isolator from Texas Instruments, featuring four forward channels and one reverse channel in a 16-pin SSOP package. It operates on a supply voltage range of 2.7 V to 5 V with a maximum data rate of 50 Mbps. The device provides 2500 Vrms insulation via capacitive coupling and supports an operating temperature range from -40°C to +125°C. Key electrical parameters include a propagation delay of 23 ns, a common-mode transient immunity (CMTI) of 25 kV/µs, and a typical quiescent current of 14 mA.

Digital Isolators Feature Summary

• Integrated noise filter for robust design
• Default output low option available
• Small-footprint and low-power architecture

Digital Isolators Applications

• Industrial automation systems
• Medical equipment isolation
• Power metering circuits

Digital Isolators Procurement Notes

Verify the specific suffix 'F' indicates the default output low feature when sourcing. Confirm the 'DBQ' suffix corresponds to the SSOP-16 package variant. Ensure compatibility with the required insulation voltage ratings for your application safety standards before finalizing procurement.

Digital Isolators Selection Notes

Select this component for applications requiring high-speed data transmission up to 50 Mbps with moderate power consumption. The quad-forward and single-reverse channel configuration suits asymmetric communication needs. Consider the 2500 Vrms rating for basic isolation requirements rather than reinforced isolation standards.

Digital Isolators Part Context

This part belongs to the ISO714x family of small-footprint digital isolators. It shares the same physical package and core isolation technology as other variants in the series but differs in channel count and directionality. The family is designed to replace traditional optocouplers in space-constrained designs.

Digital Isolators Replacement Considerations

Direct replacements within the same family include ISO7141FCCDBQR for tape-and-reel packaging. Other variants like ISO7140 or ISO7141 without the 'F' suffix offer different output states. Verify pinout compatibility when substituting with non-TI isolators.
