Description
The Intersil ISL3282EMRTEP is a ±16. 5kV IEC61000 ESD protected, 3. 0V to 5. 5V powered, single receiver that meets both the RS-485 and RS-422 standards for balanced communication. This receiver has very low bus currents (+125μA/-100μA), so it presents a true “1/8 unit load” to the RS-485 bus. This allows up to 256 receivers on the network without violating the RS-485 specification’s 32 unit load maximum and without using repeaters. Receiver inputs feature a “Full Fail-Safe” design, which ensures a logic high Rx output if Rx inputs are floating, shorted, or terminated but undriven. The ISL3282EMRTEP includes an active low enable pin and is offered in the Military Temperature range (-55°C to +125°C). A 26% smaller footprint is available with the TDFN package. This device also features a logic supply pin (VL) that sets the VOH level of the RO output (and the switching points of the RE/RE input) to be compatible with another supply voltage in mixed voltage systems. Device Information The specifications for an Enhanced Product (EP) device are defined in a Vendor Item Drawing (VID), which is controlled by the Defense Supply Center in Columbus (DSCC). “Hot-links” to the applicable VID and other supporting application information are provided on our website.

- 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.
