HIN238CBZ-T is a galvanic-isolated, bus transceiver from Texas Instrument, which is compatible with RS-485 serial applications. It is designed with fault-tolerant differential communications schemes to accomplish reliable performance.

The HIN238CBZ-T application field mainly includes industrial automation networks, industrial control, telecommunications, and automatic test equipment (ATE). It can also be used in smart grid systems.

HIN238CBZ-T features robust system-level noise immunity, which is protected against transient voltage/current induced errors, ensuring reliable performance over a wide temperature range of -40°C to 85°C. Its suppress EMI/RFI emission and guarantee high-level circuit component compatibility. Moreover, the product provides integrated overvoltage and undervoltage protection to protect against faulty signal lines.

Working Principle

The HIN238CBZ-T features three operating modes. It acts as a receiver in one mode and as a transmitter in another. In its third mode, it acts as both a receiver and a transmitter. A bidirectional communication link is established in this mode.

The transceiver is based on transmitters and receivers specifically designed for RS-485 applications. In the receiver mode, it has a differential input stage with a high-frequency roll-off that eliminates the need for external components. When in transmitter mode, it sinks current onto the bus rather than sourcing current, making the product well-suited to applications that do not require robust communication. This further reduces power consumption.

To ensure reliable performance, the transceiver has an adaptive hysteresis level control that compensates for the changing common mode voltage level on the bus. Basically, this feature ensures that the receiver is never falsely triggered. In addition, the receiver has an adjustable time-out period for detecting line conditions that guarantee correct data transmission.

Conclusion

The HIN238CBZ-T is an interface driver, receiver, transceiver, which is suitable for various applications. It has three operating modes that enable it to act as a receiver, a transmitter or both, giving you the flexibility to customize your serial connection. In addition, the product features robust noise immunity, integrated overvoltage and undervoltage protection, as well as an adaptive hysteresis level control. Therefore, it is a reliable product for serial applications.
