描述
The HIN232-HIN241 family of RS-232 transmitters/receivers interface circuits meet all ElA RS-232E and V. 28 specifications, and are particularly suited for those applications where ±12V is not available. They require a single +5V power supply (except HIN239) and feature onboard charge pump voltage converters which generate +10V and -10V supplies from the 5V supply. The family of devices offer a wide variety of RS-232 transmitter/receiver combinations to accommodate various applications. The drivers feature true TTL/CMOS input compatibility, slewrate- limited output, and 300Ω power-off source impedance. The receivers can handle up to ±30V, and have a 3kΩ to 7kΩ input impedance. The receivers also feature hysteresis to greatly improve noise rejection.

- 应用说明英语PDF 365 KB AN1978 2023年4月12日AI 生成的摘要: The document details surge protection circuits for RS-485 transceivers, focusing on Level 4 (4kV) protection using gas discharge tubes (GDTs) for higher overvoltage and overcurrent tolerance. It compares protection schemes by component count, board area, and cost, highlighting that higher-level protection increases complexity and expense. The BOMs for Level 3 and Level 4 circuits list components such as transceivers, bidirectional TVS diodes, transient blocking units, thyristors or GDTs, and resistors. The GDT switching characteristic explains how it diverts transient currents to ground by transitioning from high impedance to a crowbar current path. Simpler protection can be achieved with overvoltage protected transceivers.
- 应用说明英语PDF 207 KB an1985 2022年8月19日AI 生成的摘要: Transient protection for RS-485 transceivers involves careful TVS diode design to prevent damage from high surge currents. Internal ESD structures in the ISL3152E share transient current with external TVS diodes, risking damage without current-limiting resistors. Using thick-film resistors under 200 ohms between TVS and transceiver limits surge current while minimizing bus voltage attenuation. Recommended PCB layout includes low-inductance ground and Vcc planes, 0603 resistors for wave or reflow soldering, and proper component placement to reduce inductance and enhance protection.

It details the use of TVS diodes and thyristors to protect data lines against surge currents while maintaining low capacitance for high data rates. Different configurations address various common-mode voltage ranges and surge levels, ensuring compliance with IEC61000-4-5 standards. The paper includes calculations for peak protection voltages and discusses device characteristics and combinations for robust surge protection in industrial applications.
