ISO7810DWR

Overview

The ISO7810DWR is a single-channel digital isolator from Texas Instruments, housed in a 16-pin SOIC package. It operates on a supply voltage range of 2.25 V to 5.5 V with a typical operating current of 5.7 mA. The device supports data rates up to 100 Mb/s and features a propagation delay of 10.7 ns. It provides an insulation voltage of 5700 Vrms using capacitive coupling technology. The component functions within a temperature range of -55°C to +125°C and offers a common-mode transient immunity of 100 kV/µs.

Feature Summary

• Provides galvanic isolation between circuits using capacitive coupling technology
• Supports high-speed data transmission at rates up to 100 Mb/s
• Features unidirectional signal flow for single-channel applications
• Operates reliably across an extended industrial temperature range

Applications

• Industrial automation systems requiring isolated communication
• Medical equipment needing reinforced electrical isolation
• Power metering circuits with high-voltage separation requirements
• Inverter drives and motor control interfaces

Procurement Notes

Verify the specific suffix DWR indicates the SOIC-16 package and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure design compatibility with the specified 2.25 V to 5.5 V supply voltage range. Check for moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this component when a single-channel solution with high isolation voltage is required. Compare against multi-channel variants like ISO7820 or ISO7840 if additional channels are needed. Consider the 100 Mb/s data rate limit for bandwidth requirements. Evaluate power consumption differences against other isolator families for efficiency optimization.

Part Context

This part belongs to the ISO78xx family of high-performance digital isolators. It shares the same SOIC-16 footprint and basic isolation characteristics as other members like ISO7820 and ISO7840. The primary distinction lies in the channel count, with this model offering only one isolated path. It complements Texas Instruments' broader portfolio of interface and isolation solutions.

Replacement Considerations

Direct substitutes include ISO7810DW for tape-and-reel variations or ISO7810DR for alternative packaging options. Cross-reference with ISO7811 for bidirectional capabilities if signal directionality changes are required. Verify pinout compatibility when replacing legacy components in existing designs.
