ISO7810DW

Overview

The ISO7810DW is a single-channel digital isolator from Texas Instruments, housed in a 16-pin SOIC (DW) package. It utilizes capacitive coupling technology to provide an insulation voltage of 5700 Vrms and supports data rates up to 100 Mb/s. The device operates within a supply voltage range of 2.25 V to 5.5 V, drawing a typical operating current of 5.7 mA. Key electrical specifications include a propagation delay of 10.7 ns, rise and fall times of 3.9 ns, and pulse width distortion of 600 ps. It functions unidirectionally without a shutdown feature and is rated for an extended operating temperature range from -55°C to +125°C.

Feature Summary

• Provides reinforced digital isolation with high insulation ratings certified by VDE, CSA, and CQC standards.
• Utilizes capacitive coupling technology for reliable signal transmission across isolation barriers.
• Supports high-speed data communication at rates up to 100 Mb/s with low propagation delay.

Applications

• Isolation of CMOS or LVCMOS digital I/O interfaces
• General-purpose digital isolation in industrial systems
• Signal isolation in measurement and control applications

Procurement Notes

Verify the specific ordering suffix to confirm the package type and tape/reel configuration, as variants such as DWR differ from DW. Ensure compliance with RoHS directives and check humidity sensitivity classification for proper storage handling. Confirm that the selected part matches the required insulation certification standards for your application safety requirements.

Selection Notes

Select this component when a single-channel, unidirectional isolator with high voltage withstand capability is required. Consider the 16-pin SOIC footprint for board space constraints. Evaluate the 5700 Vrms insulation rating against system safety standards. Compare power consumption and data rate needs against other channels if multiple isolators are needed, noting that quad-channel alternatives exist in the same family.

Part Context

The ISO7810DW belongs to the ISO7810 series of high-performance digital isolators manufactured by Texas Instruments. This series is designed for robust signal isolation in noisy environments. The DW package variant specifically denotes the 16-lead Small Outline Integrated Circuit format, distinguishing it from reel-packaged versions like the DWR suffix.

Replacement Considerations

The ISO7810DWR serves as a direct functional substitute with identical electrical characteristics but differs in packaging format (reel vs. tube). For multi-channel requirements, the ISO7840DW offers four channels within the same family architecture.
