SN751177N

Drivers, Receivers, Transceivers Overview

The SN751177N is a dual differential driver and receiver pair from the Texas Instruments SN751177 series, designed for RS-422 and RS-485 communication applications. It operates on a single 5V supply with a voltage range of 4.75V to 5.25V. The device features full-duplex operation with two transmitters and two receivers, supporting data rates up to 10 Mbps. It accommodates up to 32 nodes on the bus and provides fault protection within a -10V to +15V common-mode range. The component is housed in a 16-pin PDIP package and functions reliably across an operating temperature range of -20°C to 85°C.

Drivers, Receivers, Transceivers Feature Summary

• Supports full-duplex differential signaling for robust noise immunity in industrial environments
• Provides integrated fault protection against short circuits and common-mode voltage deviations
• Enables high-speed data transmission up to 10 Mbps over balanced transmission lines

Drivers, Receivers, Transceivers Applications

• RS-422 and RS-485 multi-drop communication networks
• Industrial automation and control systems requiring reliable serial data exchange
• Building automation and security system interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature rating. Ensure the procurement channel sources genuine Texas Instruments components to guarantee electrical performance and reliability standards are met for critical interface applications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex operation is required compared to half-duplex alternatives like the SN75176. Consider the PDIP package for through-hole mounting requirements. Verify that the 10 Mbps speed and 32-node limit align with the specific network topology and bandwidth demands of the design.

Drivers, Receivers, Transceivers Part Context

This part belongs to the legacy SN75xx logic family, widely used for standard RS-422/RS-485 interfaces. It serves as a foundational component for serial communication in older industrial equipment and remains relevant for maintenance and retrofit projects where through-hole packaging is preferred.

Drivers, Receivers, Transceivers Replacement Considerations

The SN751178 is a direct functional equivalent within the same series. Verify if the commercial grade (0°C to 70°C) of the SN751178 meets the thermal requirements, as the SN751177N supports an extended range down to -20°C.
