DS75176BTMX/NOPB Description

The DS75176BTMX/NOPB from Texas Instruments is a half-duplex RS-422/RS-485 transceiver designed for robust differential data communication in industrial and embedded systems. Housed in an 8-pin SOIC package, this surface-mount IC integrates one driver and one receiver, supporting high-speed data transmission with a supply voltage range of 4.75V to 5.25V. It features 70 mV of receiver hysteresis, enhancing noise immunity in electrically noisy environments. Although marked as obsolete, it remains a reliable choice for legacy designs due to its ROHS3 compliance and REACH-unaffected status.

DS75176BTMX/NOPB Features

• Half-Duplex Operation: Enables bidirectional communication over a single twisted-pair line, reducing wiring complexity.
• Wide Protocol Support: Compatible with RS-422 and RS-485 standards, ideal for multi-point networks.
• Enhanced Noise Immunity: 70 mV receiver hysteresis minimizes signal errors in high-interference settings.
• Low Power Consumption: Optimized for efficiency in 5V systems.
• Robust Packaging: Tape & Reel (TR) delivery ensures suitability for automated assembly.
• Industrial Compliance: EAR99 and HTSUS 8542.39.0001 classifications facilitate global deployment.
