ISO7830FDWWR

Overview

The ISO7830FDWWR is a high-performance, triple-channel digital isolator from Texas Instruments. It features capacitive coupling technology with a maximum data rate of 100 Mb/s and a common-mode transient immunity of 100 kV/µs. The device operates within a supply voltage range of 2.25 V to 5.5 V and draws a typical operating current of 17.5 mA. It provides an insulation voltage rating of 5700 Vrms and supports bidirectional signal transmission across three forward channels. The component is housed in a 16-pin SOIC package and functions reliably within a temperature range of -55°C to +125°C.

Feature Summary

• Provides reinforced electrical isolation for high-voltage noise immunity
• Supports high-speed data transmission up to 100 Mb/s
• Features low propagation delay for precise timing control
• Integrates three independent unidirectional channels in a compact package

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety barriers
• Power metering circuits for accurate signal measurement
• Inverter drives and motor control applications

Procurement Notes

Verify the specific suffix 'DWWR' corresponds to the SOIC-16 package and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification. Cross-reference pinout diagrams with target PCB layout requirements to prevent installation errors.

Selection Notes

Select this component when three isolated channels are required for single-supply operation. Compare power consumption against alternative isolators if battery life is critical. Evaluate the 5700 Vrms insulation rating against system safety standards. Consider the 100 kV/µs CMTI specification for environments with rapid voltage switching transients.

Part Context

This part belongs to the ISO78x0 family of digital isolators designed for robust performance in noisy environments. It complements other variants like the ISO7810 (single channel) and ISO7840 (quad channel) within the same series. The family shares similar interface characteristics but varies in channel count and power efficiency to suit different integration densities.

Replacement Considerations

Direct substitutes include ISO7830FDWWT for tape-and-reel variations or ISO7831FDWWR for dual-forward/single-reverse configurations. Verify pin compatibility and insulation ratings when considering cross-series replacements.
