AM26C32CN Description

The AM26C32CN from Texas Instruments is a quad differential line receiver designed for robust data transmission in industrial and communication systems. It operates within a 4.5V to 5.5V supply range and supports RS422 and RS423 protocols, making it ideal for noise-immunity-critical applications. Housed in a 16-pin DIP (Through Hole) package, this obsolete but reliable component features 60 mV of receiver hysteresis, enhancing signal integrity in electrically noisy environments. With an operating temperature range of 0°C to 70°C, it is suited for moderate industrial conditions.

AM26C32CN Features

• High Noise Immunity: Built-in 60 mV hysteresis minimizes false triggering in noisy conditions.
• Wide Supply Range: Operates at 4.5V–5.5V, compatible with standard TTL/CMOS logic levels.
• Quad Receiver Configuration: 0 drivers / 4 receivers for balanced differential signal reception.
• Protocol Support: Optimized for RS422 and RS423 standards, ensuring reliable long-distance communication.
• Robust Packaging: Through-hole 16-DIP for secure mounting in industrial PCBs.
• Compliance: ROHS3 Compliant and REACH Unaffected, meeting environmental standards.

AM26C32CN Applications

• Industrial Automation: Used in motor control systems and PLCs for noise-resistant data transmission.
• Telecommunications: Ensures signal integrity in legacy RS422/RS423 communication networks.
• Test & Measurement Equipment: Provides stable signal reception in oscilloscopes and data loggers.
• Medical Devices: Reliable for low-error data acquisition in diagnostic equipment.
• Military/Aerospace (Legacy Systems): Suitable for older avionics and defense communication systems.

Conclusion of AM26C32CN

The AM26C32CN remains a dependable choice for differential signal reception despite its obsolete status. Its high noise immunity, wide voltage tolerance, and robust packaging make it ideal for industrial, telecom, and legacy systems requiring stable data transmission. While newer alternatives exist, this receiver’s proven performance in harsh environments ensures continued relevance in specific applications. Engineers seeking a cost-effective, noise-resistant solution for RS422/RS423 implementations should consider this IC for retrofits or long-lifecycle designs.
