Overview

The ISL3152EIBZ-T is a low-power, half-duplex RS-485/RS-422 transceiver designed for robust data communication at rates up to 115Kbps. It operates from a single 5V supply and features a high input impedance that allows up to 256 devices on a single bus. The device is specifically engineered for high reliability with integrated ESD protection and full fail-safe receiver inputs.

Why Choose This Part

This transceiver offers a significant power advantage with a 0.7mA supply current and a 70nA low-power shutdown mode. It includes hot-plug capability to ensure bus integrity during live insertion and fail-safe circuitry that guarantees a logic high output when inputs are shorted or floating.

Applications

Automated Utility Metering
Ideal for e-meter reading systems requiring low power consumption and high node density on the communication bus.
Industrial Fieldbus Systems
Used in PROFIBUS and factory automation environments where long-distance differential signaling is required.
Security and Surveillance
Facilitates half-duplex control of PTZ cameras and security sensors over twisted-pair cabling.
High Node Count Networks
Supports up to 256 units on a bus due to its 1/8 unit load input characteristics.

Getting Started

To evaluate this part, design a PCB with standard 8-SOIC footprints and include a 120-ohm termination resistor at the cable ends. Ensure a 0.1uF decoupling capacitor is placed close to the VCC pin and manage the DE and /RE pins through a microcontroller GPIO for half-duplex direction control.
