Description
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.

- Application NotePDF 365 KB AN1978 Apr 12, 2023AI-generated Summary: 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.
- Application NotePDF 207 KB an1985 Aug 19, 2022AI-generated Summary: 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.
- Application NotePDF 474 KB AN1979 Aug 16, 2022AI-generated Summary: The document explains surge protection using Renesas’ Overvoltage Protected (OVP) transceivers with various protection schemes. 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.

It recommends balancing common-mode impedance with two current setting resistors for improved common-mode rejection. The PS9121 optocoupler supports 3.75kV isolation and up to 15Mbps data rate, paired with the ICL3221 RS-232 transceiver operating at 250kbps. It details calculating resistor values for LED current and pull-up resistors to optimize performance and reduce power consumption. Signal waveforms demonstrate the isolated interface operation.
- Application NotePDF 513 KB an1991 Mar 06, 2018AI-generated Summary: The document explains the design of LED drive circuits for high-speed digital optocouplers in RS-485 interfaces, focusing on common-mode rejection (CMR) improvement by balancing impedance with two resistors. It details an isolated RS-485 interface using PS9924 optocouplers and ISL3155 transceivers, highlighting dominant/recessive mode operation and bus arbitration. It provides calculations for current setting resistors and collector resistors to optimize performance, minimize propagation delay, and reduce pulse width distortion for reliable data transmission up to 10Mbps.
