ISO6760LDWR

Overview

The ISO6760LDWR is a six-channel reinforced digital isolator from Texas Instruments, housed in a 16-pin SOIC package. It operates at data rates up to 50 Mbps with an isolation voltage of 5000 Vrms and common-mode transient immunity of 50 kV/µs. The device features integrated interlock functionality for all forward channels, ensuring safe operation during power-down states. It supports supply voltages between 1.71 V and 5.5 V and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrated interlock mechanism prevents false triggering by disabling outputs when the device is unpowered or below threshold.
• Reinforced insulation design provides high electromagnetic immunity and low emissions for reliable signal transmission.
• Capacitive coupling technology enables bidirectional or unidirectional data transfer across isolated boundaries.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety barriers
• Power electronics control circuits

Procurement Notes

Verify the specific suffix 'LNDWR' versus 'LDWR' against official datasheets, as variations may indicate different packaging or regional specifications. Confirm RoHS compliance status directly with the manufacturer documentation before procurement. Ensure ESD handling protocols are followed due to moisture sensitivity classification.

Selection Notes

Select this component when six independent isolated channels are required in a single package. The integrated interlock feature is critical for applications demanding fail-safe behavior during power loss. Compare propagation delay and power consumption against other ISO67xx series variants to match system timing and thermal constraints.

Part Context

This part belongs to the ISO6760 family of digital isolators designed for high-reliability applications. It complements other Texas Instruments isolation products by offering a compact solution for multi-channel isolation needs without compromising on safety standards or signal integrity.

Replacement Considerations

Check for direct pin-compatible substitutes within the ISO676x series. Verify that alternative parts support the same 5000 Vrms isolation rating and 50 Mbps data rate. Ensure the replacement also includes the integrated interlock feature if required by the design.

FAQ

What is the function of the integrated interlock?

The integrated interlock disables the output drivers when the device is not powered or operating below the specified voltage threshold, preventing unintended signal transmission.

Is the ISO6760LDWR suitable for medical applications?

Yes, it offers reinforced insulation ratings compliant with safety standards often required in medical equipment, provided the overall system design meets relevant regulatory requirements.
