ISO7830DWWR

Overview

The ISO7830DWWR is a quad-channel digital isolator from Texas Instruments, housed in a 16-pin SOIC package. It provides high isolation ratings with an insulation voltage of 5700 Vrms and operates at data rates up to 100 Mb/s. The device supports a wide supply voltage range from 2.25 V to 5.5 V and functions within an extended temperature range of -55°C to +125°C. Key electrical parameters include a typical propagation delay of 11 ns, rise/fall times of approximately 3.9 ns, and a maximum power dissipation of 150 mW. It utilizes capacitive coupling for signal transmission.

Feature Summary

• Offers highest isolation rating for robust signal integrity
• Provides triple-channel unidirectional signal isolation
• Supports wide supply voltage translation from 2.25 V to 5.5 V
• Features high common-mode transient immunity

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing high-voltage safety isolation
• Power metering applications with isolated communication interfaces
• Inverter drives and motor control circuits

Procurement Notes

Verify the specific suffix 'DWR' confirms the reel packaging format upon ordering. Ensure compatibility with moisture sensitivity levels as indicated in the datasheet. Confirm that the 16-SOIC footprint matches the target PCB design constraints. Validate that the operating temperature range meets the environmental requirements of the final assembly.

Selection Notes

Select this component when triple-channel isolation is required alongside high voltage withstand capabilities. The 100 Mbps signaling rate suits moderate-speed digital communication needs. Consider the 16-pin SOIC package for surface-mount assembly efficiency. Evaluate the 5700 Vrms insulation rating against system safety standards.

Part Context

This part belongs to the ISO78xx family of digital isolators designed for high-reliability applications. It complements other variants like the ISO7840 (quad-channel) and ISO7831 (bidirectional). The series emphasizes compact size and low power consumption while maintaining strict isolation barriers for industrial and medical environments.

Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio. Verify if updated revisions offer improved thermal performance or packaging options. Ensure substitute parts maintain the same 5700 Vrms isolation rating and 100 Mbps data rate specifications.
