ST202BTR

ST202BTR Description

The ST202BTR from STMicroelectronics is a high-performance RS232 transceiver designed for robust serial communication in demanding industrial and commercial applications. This surface-mount (SMT) device integrates 2 drivers and 2 receivers in a compact 16-pin TSSOP package, making it ideal for space-constrained designs. Operating within a 4.5V to 5.5V supply range, it supports full-duplex communication at data rates up to 400kbps, ensuring reliable data transmission in noisy environments. Compliant with ROHS3 and REACH regulations, the ST202BTR is suitable for global markets, with an ECCN EAR99 classification for export control.

ST202BTR Features

• Full-duplex RS232 transceiver with 500mV receiver hysteresis for enhanced noise immunity.
• Wide supply voltage range (4.5V–5.5V), compatible with standard 5V systems.
• High-speed data rate (400kbps) for efficient serial communication.
• Surface-mount 16TSSOP package for compact PCB layouts.
• RoHS3 and REACH compliant, meeting environmental and safety standards.
• Moisture Sensitivity Level (MSL 1), allowing unlimited floor life before reflow.
• Tape & Reel (TR) packaging for automated assembly processes.

ST202BTR Applications

The ST202BTR excels in applications requiring robust serial communication, such as:

• Industrial automation (PLC interfaces, motor control).
• Telecom infrastructure (modems, routers, base stations).
• Point-of-sale (POS) systems and barcode scanners.
• Medical equipment requiring reliable data transmission.
• Embedded systems with RS232 interfaces.
  Its high noise immunity and wide operating voltage make it superior to older RS232 transceivers, particularly in electrically noisy environments.

Conclusion of ST202BTR

The ST202BTR is a versatile, high-performance RS232 transceiver offering reliability, compactness, and compliance with modern environmental standards. Its full-duplex operation, robust hysteresis, and industrial-grade durability make it a preferred choice for engineers designing communication-heavy systems. Whether for industrial, telecom, or embedded applications, the ST202BTR delivers exceptional signal integrity and ease of integration.
