ISO7141FCCDBQR

Overview

The ISO7141FCCDBQR is a low-power, small-footprint digital isolator from Texas Instruments featuring four channels in an SSOP-16 package. It provides three unidirectional forward channels and one reverse channel with a maximum signaling rate of 50 Mbps. The device operates on a single supply voltage ranging from 2.7 V to 5 V, drawing a typical quiescent current of 14 mA per side. It offers reinforced insulation capabilities with a rated isolation voltage of 2500 Vrms and utilizes capacitive coupling technology. The component supports an operating temperature range from -40°C to +125°C and includes integrated noise filtering for robust signal integrity.

Feature Summary

• Integrated noise filter for enhanced signal reliability
• Default output low configuration option
• Small-footprint design suitable for space-constrained applications

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing functional or reinforced isolation
• General-purpose digital communication interfaces

Procurement Notes

Verify the specific suffix 'F' confirms the default output low feature as documented in the official datasheet. Ensure the SSOP-16 package matches your PCB footprint requirements. Confirm humidity sensitivity handling procedures are followed during assembly. Cross-reference the exact part number with manufacturer specifications to avoid confusion with non-F variants.

Selection Notes

Select this component when a low-power solution with integrated noise filtering is required for unidirectional data transmission. The 50 Mbps data rate suits standard industrial protocols. Consider the 2500 Vrms insulation rating for safety-critical applications. The SSOP-16 package offers a compact alternative to wider SOIC packages while maintaining similar electrical performance characteristics.

Part Context

This device belongs to the ISO7141CC family of digital isolators designed for general-purpose applications. It complements higher-speed variants like the ISO7741 series by offering a cost-effective solution for lower bandwidth needs. The family emphasizes low power consumption and small physical size, making it suitable for dense circuit board layouts where thermal management and space are critical constraints.

Replacement Considerations

Direct replacements include other ISO7141 variants with different suffixes indicating package or feature changes. Verify that substitute parts maintain the same 50 Mbps data rate and 2500 Vrms insulation rating. Check if the default output state matches system requirements, as the 'F' suffix specifically denotes default low outputs.
