AD260BND-5

Overview

The AD260BND-5 is a high-speed digital isolator from Analog Devices, utilizing IsoLogic circuit architecture to isolate five digital control signals. It features magnetic coupling with an integrated isolated power transformer providing up to 1.5 W at 37 V p-p. The device supports a logic signal bandwidth of 20 MHz and offers a common-mode transient immunity of 10 kV/ms. It operates on a single 5 V supply with a current consumption of 4 mA. The component is housed in a 22-pin PDIP package and is rated for operation between -25°C and +85°C.

Feature Summary

• Integrates five isolated logic lines with an internal power transformer for simultaneous signal and power isolation
• Employs IsoLogic magnetic coupling technology to achieve high common-mode transient immunity
• Provides unidirectional signal transmission with general-purpose logic compatibility

Applications

• PLC and DCS analog input/output cards
• IGBT motor drive controls
• High-speed digital I/O ports
• Communications bus isolation

Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and configuration. Confirm RoHS compliance status as indicated in current manufacturer records. Check for obsolescence notices or lifecycle changes prior to finalizing design-in decisions. Ensure the PDIP-22 package footprint matches the target PCB layout requirements.

Selection Notes

Select this component when designing systems requiring simultaneous isolation of multiple digital channels and isolated power delivery within a single package. It serves as a direct replacement for multiple discrete opto-isolators. Consider the 20 MHz bandwidth and 10 kV/ms CMTI for noisy industrial environments. Verify that the 5 V supply voltage aligns with the system's power architecture.
