TRSF3232EIDBR Description

The TRSF3232EIDBR from Texas Instruments is a high-performance, full-duplex RS-232 transceiver designed for robust serial communication in industrial and embedded systems. Housed in a compact 16-SSOP package, this surface-mount IC integrates 2 drivers and 2 receivers, supporting data rates up to 1 Mbps. Operating across a 3V to 5.5V supply range, it ensures compatibility with both 3.3V and 5V logic systems. Despite its obsolete status, it remains a reliable choice for legacy designs, offering 300 mV receiver hysteresis for enhanced noise immunity in electrically noisy environments. Compliant with ROHS3 and REACH standards, it is suitable for global applications.

TRSF3232EIDBR Features

• Full-Duplex Operation: Enables simultaneous transmission and reception for efficient bidirectional communication.
• Wide Voltage Range (3V–5.5V): Flexible power supply compatibility simplifies integration into mixed-voltage systems.
• High Noise Immunity: 300 mV receiver hysteresis minimizes errors in noisy industrial environments.
• Compact SSOP-16 Package: Saves board space while maintaining robust performance.
• 1 Mbps Data Rate: Ideal for mid-speed serial communication in legacy and embedded applications.
• ROHS3 & REACH Compliant: Meets stringent environmental and safety standards.

TRSF3232EIDBR Applications

This transceiver excels in systems requiring reliable RS-232 communication, including:

• Industrial Automation: PLCs, motor controllers, and sensor interfaces where noise immunity is critical.
• Legacy Equipment: Upgrading or maintaining older systems with RS-232 ports.
• Embedded Systems: Microcontroller-based designs needing robust serial connectivity.
• Point-of-Sale (POS) Terminals: Secure data transmission in retail and banking hardware.
• Medical Devices: Patient monitoring systems requiring stable, noise-resistant communication.

Conclusion of TRSF3232EIDBR

The TRSF3232EIDBR balances performance and durability, making it a pragmatic choice for noise-prone environments and legacy upgrades. While marked obsolete, its wide voltage range, hysteresis, and compact form factor ensure continued relevance in industrial and embedded applications. Engineers seeking a proven RS-232 solution with low-risk compliance (ROHS3/REACH) will find this transceiver a dependable option.
