ISO6761DWR

Overview

The ISO6761DWR is a general-purpose six-channel reinforced digital isolator from Texas Instruments, housed in a 16-pin SOIC (DW) package. It supports a data rate of 50 Mbps with propagation delays of 15 ns and rise/fall times of 4.7 ns. The device operates on a supply voltage range of 1.71 V to 5.5 V, drawing typical currents of 8.3 mA and 16.6 mA. It features an insulation voltage of 1500 Vrms and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Provides robust electromagnetic compatibility for reliable signal transmission
• Supports bidirectional logic operation for flexible interface configurations
• Offers reinforced isolation ratings for safety-critical applications

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing high-reliability signal barriers
• Power electronics interfaces for motor control circuits

Procurement Notes

Verify the specific suffix DWR corresponds to the SOIC-16 tape-and-reel packaging configuration. Confirm that the 1500 Vrms insulation rating meets your system's safety requirements rather than assuming higher ratings found in other family members. Ensure input voltage levels align with the specified 1.71 V to 5.5 V operating range for proper logic threshold compliance.

Selection Notes

Select this component when a six-channel isolator with moderate speed and standard reinforcement ratings is required. Compare against the ISO7761 series if higher insulation voltages or faster data rates are necessary. Consider the ISO6760 series if lower power consumption is prioritized over the specific channel count or isolation rating provided by the ISO6761.

Part Context

This part belongs to the ISO676x family of general-purpose six-channel digital isolators. It shares the same physical footprint and basic functionality as variants like the ISO6760 and ISO6762 but differs in specific electrical characteristics such as insulation voltage and current consumption. The DW package designation indicates a standard small-outline integrated circuit form factor suitable for surface-mount assembly.

Replacement Considerations

Direct substitutes include the ISO6760DWR and ISO6762DWR within the same TI family. Verify that the replacement variant matches the required insulation voltage and channel configuration before implementation.
