ISO7810DWWR

Overview

The ISO7810DWWR is a high-performance, single-channel digital isolator manufactured by Texas Instruments. It features reinforced insulation with a rating of 5700 Vrms and supports data rates up to 100 Mbps. The device operates within a supply voltage range of 2.25 V to 5.5 V and exhibits a propagation delay of 10.7 ns. It offers a common-mode transient immunity of 100 kV/µs. The component is housed in a 16-pin SOIC package with a width of 14.00 mm and functions reliably across an operating temperature range from -55°C to +125°C.

Feature Summary

• Provides reinforced insulation for safety-critical applications
• Delivers high common-mode transient immunity
• Supports unidirectional signal transmission

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced electrical safety barriers
• Power management circuits with isolated feedback loops

Procurement Notes

Verify the specific suffix 'W' indicates the reel packaging configuration distinct from tube variants. Confirm that the 16-SOIC package dimensions align with PCB footprint requirements. Ensure the 5700 Vrms insulation rating meets the specific safety standards required by the target application environment. Cross-reference the datasheet revision to confirm parameter consistency.

Selection Notes

Select this component when a single channel of reinforced isolation is sufficient for the design. Consider the 100 Mbps data rate limit for signal integrity requirements. Evaluate the 10.7 ns propagation delay against timing constraints. Compare power consumption characteristics against other isolator families if low standby current is critical.

Part Context

This part belongs to the ISO78xx family of digital isolators from Texas Instruments. It shares architectural similarities with multi-channel variants like the ISO7820 and ISO7840 but provides only one isolated channel. The DWWR suffix denotes the specific tape-and-reel packaging format for automated assembly.

Replacement Considerations

The ISO7810DWR is a compatible alternative differing primarily in tube packaging rather than electrical performance. Verify pinout compatibility and thermal characteristics before substitution.
