SN65LBC173AMDREP

Drivers, Receivers, Transceivers Overview

The SN65LBC173AMDREP is a quad low-power differential line receiver manufactured by Texas Instruments, designed for RS-422 and RS-485 communication interfaces. It operates with a fixed supply voltage of 5 V and supports data transmission rates up to 50 Mb/s. The device functions within an extended industrial temperature range from -55°C to +125°C, ensuring reliability in harsh environments. Packaged in a 16-pin SOIC (Narrow) surface-mount format, it draws a typical operating supply current of 20 mA. This component lacks a shutdown feature and is classified as a military-enhanced repeater product.

Drivers, Receivers, Transceivers Feature Summary

• Supports high-speed differential signaling for robust noise immunity in industrial networks
• Engineered for extended thermal stability suitable for demanding operational conditions
• Optimized for low power consumption during continuous operation

Drivers, Receivers, Transceivers Applications

• Military-grade RS-485 bus network receivers
• Industrial control systems requiring wide temperature tolerance
• RS-422 multi-drop communication links

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific AMDREP suffix designation to confirm military-grade qualification and enhanced testing requirements prior to integration. Confirm that the procurement channel provides traceability documentation consistent with defense or aerospace standards. Ensure compatibility with existing board layouts utilizing the 16-SOIC package dimensions. Validate that the supply source adheres to authorized distribution protocols for restricted component categories.

Drivers, Receivers, Transceivers Selection Notes

Select this component when application requirements mandate operation across the full -55°C to +125°C temperature spectrum. Choose this part over standard commercial variants if long-term reliability under extreme thermal cycling is critical. Ensure the system design accommodates the 5 V single-supply requirement and the 20 mA quiescent current draw. Verify that the 50 Mb/s data rate aligns with the network topology speed constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SN65LBC173A series of low-power differential receivers. The AMDREP suffix indicates a military-reliability grade variant, distinct from standard commercial or industrial versions like the SN65LBC173AD. It serves as a specialized interface solution for applications where standard commercial components fail to meet environmental durability standards.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include other military-grade variants within the same family, such as the SN65LBC173AMDR. Standard commercial equivalents like the SN65LBC173AD offer identical electrical performance but lack the extended temperature range and military qualification.
