• Provides low-power operation for energy-efficient applications
• Features half-duplex data transmission capability

Applications

• Industrial automation control systems
• Building management and security networks
• Data acquisition and monitoring equipment

Procurement Notes

Verify the specific suffix 'TN' against the manufacturer's official documentation to confirm the exact package type and tape/reel specifications. Ensure that the component meets all required environmental standards for the intended deployment environment before finalizing procurement decisions.

Selection Notes

Select this component when a robust, low-power interface is required for multipoint serial communication. Consider the 8-pin MDIP package constraints and the 0°C to +70°C operating temperature range to ensure compatibility with the target system's physical and thermal requirements.

Part Context

This part belongs to the DS485 series of interface ICs from Texas Instruments. It is designed for reliable data transmission in noisy industrial environments, offering a balance between performance and power consumption for standard serial communication protocols.

Replacement Considerations

Check for direct pin-compatible substitutes within the same product family or newer generations recommended by Texas Instruments. Verify electrical parameter equivalence and package dimensions before considering alternative components.
