AD260BND-0

Overview

The AD260BND-0 is a five-channel digital isolator utilizing IsoLogic magnetic coupling technology. It provides 3500 Vrms isolation voltage and supports data rates up to 20 MHz with a common-mode transient immunity of 10 kV/µs. The device operates on a single 5 V supply, drawing 4 mA of quiescent current per channel. It is housed in a 22-pin PDIP package and functions as a unidirectional logic isolator for general-purpose applications within the specified temperature range.

Feature Summary

• Integrates five independent digital channels for simultaneous signal isolation
• Employs IsoLogic architecture for robust magnetic coupling isolation
• Provides high common-mode transient immunity for noisy environments

Applications

• Isolating microcontroller control signals from peripheral devices
• General-purpose digital signal isolation in industrial systems
• Protecting low-voltage logic circuits from high-voltage domains

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific part number matches the required specifications, noting that this item is listed as obsolete. Ensure compliance with relevant regulatory standards applicable to your region before procurement.

Selection Notes

Select this component when five isolated channels are required within a single package. Consider the 3500 Vrms isolation rating and 20 MHz speed limits against system requirements. Evaluate the PDIP package constraints if surface-mount alternatives are preferred for modern assembly processes.

Part Context

This device belongs to the AD260 series of digital isolators from Analog Devices. It represents an older generation of IsoLogic-based components designed for cost-effective isolation solutions. The series focuses on providing reliable signal transfer across isolation barriers using proprietary magnetic coupling techniques.

Replacement Considerations

As the AD260BND-0 is obsolete, consider the ADUM260N1BRIZ-RL as a potential alternative. Note that the replacement offers six channels, different packaging (SOIC-16), and varying electrical characteristics compared to the original five-channel DIP component.
