ST232BTR - STMicroelectronics

The ST232BTR is a robust serial port transceiver from STMicroelectronics, designed to provide bidirectional communication capabilities for the standard V.28 and EIA/TIA-232-E communication protocols. This device is a key component in applications requiring serial port interfaces, such as point-of-sale terminals, computer peripherals, and telecommunication systems.

Constructed with a high level of integration, the ST232BTR incorporates a dual charge pump circuit that allows the transceiver to operate from a single 5V power supply while generating the necessary RS-232 voltage levels, which can reach ±10V. This feature simplifies the power supply design and reduces the overall component count, making it a cost-effective solution for many applications.

The ST232BTR is capable of data rates up to 120 kbps, ensuring compatibility with high-speed communication requirements. Additionally, it has a low-power consumption profile, with a typical supply current of 5mA, which is beneficial for power-sensitive designs. The device also includes a power-down feature that reduces the supply current to a mere 1µA, further enhancing its suitability for battery-operated equipment.

This transceiver comes in a compact and reliable TSSOP-16 package, which is suitable for space-constrained applications. Its enhanced electrostatic discharge (ESD) protection, capable of withstanding up to ±8kV on human body model (HBM), provides robustness and reliability, ensuring the longevity of the product in harsh electrical environments.

The ST232BTR also boasts a wide temperature range of -40°C to +85°C, making it suitable for industrial applications that may experience extreme operating conditions. With its impressive features, the ST232BTR from STMicroelectronics stands out as a high-performance and reliable choice for designers looking to implement RS-232 communications in their systems.

Overall, the ST232BTR transceiver is a testament to STMicroelectronics' commitment to providing high-quality, integrated circuit solutions that address the evolving needs of electronic communication systems.
