SN75179BPS Description

The SN75179BPS from Texas Instruments is a full-duplex RS-422/RS-485 transceiver designed for robust differential data communication. Housed in an 8-pin SOIC package, this obsolete but reliable IC integrates one driver and one receiver, supporting bidirectional data transmission over long distances with minimal noise interference. Operating within a 4.75V to 5.25V supply range, it is optimized for industrial and commercial applications requiring stable performance in 0°C to 70°C environments. The device features 50mV receiver hysteresis, enhancing noise immunity in electrically noisy environments. Compliant with ROHS3 and REACH standards, it is suitable for surface-mount designs with MSL 1 (unlimited) moisture sensitivity.

SN75179BPS Features

• Full-duplex operation: Enables simultaneous transmission and reception on separate differential pairs.
• RS-422/RS-485 compatibility: Supports industry-standard protocols for balanced communication.
• High noise immunity: 50mV receiver hysteresis minimizes false triggering in noisy conditions.
• Wide supply voltage range (4.75V–5.25V): Ensures stable operation in typical 5V systems.
• Surface-mount (SOIC-8) packaging: Compact and suitable for automated PCB assembly.
• Robust ESD protection: Meets or exceeds ANSI RS-485 standards for reliability.
• Low power consumption: Optimized for energy-efficient designs.

SN75179BPS Applications

• Industrial automation: PLCs, motor control, and sensor networks requiring noise-resistant communication.
• Telecom infrastructure: Base stations and repeaters leveraging RS-485 for long-distance data links.
• Building automation: HVAC systems, lighting control, and security networks.
• Medical equipment: Patient monitoring devices where signal integrity is critical.
• Legacy system upgrades: Replacement for older RS-422/485 transceivers in maintenance scenarios.

Conclusion of SN75179BPS

The SN75179BPS is a versatile, high-performance transceiver ideal for applications demanding full-duplex RS-422/485 communication with robust noise immunity. While marked obsolete, its proven reliability, ease of integration, and compliance with environmental standards make it a pragmatic choice for legacy designs or systems requiring long-term stability. Engineers seeking a balance of simplicity, durability, and industry-standard compatibility will find this IC a dependable solution for differential data transmission challenges.
