SN75196DW Description

The SN75196DW from Texas Instruments is a high-performance RS-232 transceiver designed for robust serial communication in industrial and embedded systems. Housed in a 20-pin SOIC package, this full-duplex transceiver integrates 5 drivers and 3 receivers, supporting bidirectional data transmission with a supply voltage range of 4.5V to 5.5V. It operates within a 0°C to 70°C temperature range, making it suitable for commercial and light industrial environments. The device features 500mV receiver hysteresis, enhancing noise immunity in electrically noisy conditions. Compliant with ROHS3 and REACH standards, it is ideal for applications requiring reliable, long-term availability despite its Last Time Buy status.

SN75196DW Features

• Full-duplex RS-232 communication with 5 drivers and 3 receivers.
• Wide supply voltage range (4.5V–5.5V), ensuring compatibility with standard logic levels.
• 500mV receiver hysteresis for improved noise rejection in challenging environments.
• Surface-mount (SOIC-20) packaging, optimized for compact PCB designs.
• RoHS3 and REACH compliant, meeting environmental and safety standards.
• Last Time Buy status, indicating end-of-life but still available for legacy designs.
• Moisture Sensitivity Level (MSL) 1, suitable for extended storage and handling.

SN75196DW Applications

The SN75196DW excels in systems requiring robust serial communication, such as:

• Industrial automation (PLC interfaces, motor control).
• Embedded systems (legacy equipment, diagnostic tools).
• Point-of-sale (POS) terminals and peripheral interfacing.
• Telecommunication infrastructure (modems, routers with RS-232 ports).
• Medical devices requiring noise-resistant data transmission.

Conclusion of SN75196DW

The SN75196DW is a reliable RS-232 transceiver offering noise immunity, full-duplex operation, and broad compatibility, making it a strong choice for legacy and noise-sensitive applications. While it is in Last Time Buy status, its industrial-grade performance and compliance with modern environmental standards ensure it remains a viable solution for systems requiring durable serial communication. Engineers should consider this IC for designs needing proven RS-232 functionality in space-constrained or electrically noisy environments.
