ST232ACTR - High-Performance Serial Transceiver from STMicroelectronics

The ST232ACTR is a robust serial transceiver component designed by STMicroelectronics, which is widely recognized for its reliability and performance in facilitating serial communication. This device is part of the ST232A series, known for its compatibility with the standard RS-232 protocol. The ST232ACTR is specifically engineered to convert TTL/CMOS logic levels to RS-232 signal levels and vice versa, making it an ideal choice for a variety of applications where serial communication is essential.

One of the key features of the ST232ACTR is its low-power consumption, which makes it suitable for battery-powered and portable devices. With a 5V single power supply, it offers a power-efficient solution for serial data exchange. The device supports data transfer rates up to 120 kbps, ensuring fast and efficient communication for your projects.

The ST232ACTR is equipped with a dual charge pump circuit that allows the transceiver to deliver true RS-232 performance from a single power supply ranging from 4.5V to 5.5V. This feature eliminates the need for an additional ±12V power supplies typically required for RS-232 communication, simplifying the design and reducing the overall cost of the system.

Furthermore, the transceiver provides enhanced electrostatic discharge (ESD) protection, up to ±8 kV using the human body model, which safeguards the device against damage from static electricity and enhances its durability in harsh environments. This makes the ST232ACTR particularly suitable for industrial applications where robustness is a critical factor.

The ST232ACTR comes in a small-outline package (SO-16), which is ideal for space-constrained applications. It also features a low-power shutdown mode, which further reduces power consumption when the device is not in active use.

With its combination of high-speed data transfer, low power requirements, ESD protection, and compact form factor, the ST232ACTR is a versatile serial transceiver that can be employed in a wide range of applications, including but not limited to, point-of-sale terminals, computer peripherals, and telecommunication systems.

STMicroelectronics' commitment to quality ensures that the ST232ACTR meets the stringent requirements of modern electronic communication systems, making it a reliable choice for designers and engineers looking to implement RS-232 communications in their products.
