Overview

The ISL3178EIBZ-T is a high-speed, 3.3V powered RS-485/RS-422 differential transceiver designed for balanced data transmission at rates up to 20Mbps. It features a 1/8 unit load, allowing up to 256 devices on a single bus while maintaining low quiescent and shutdown current for power-sensitive designs.

Why Choose This Part

This transceiver offers enhanced reliability with full fail-safe receiver inputs and IEC61000 ESD protection. Its low 510uA supply current and 12uA shutdown mode make it suitable for battery-backed or energy-efficient industrial equipment.

Applications

High-Speed Industrial Networks
Ideal for RS-485 bus systems requiring 20Mbps throughput in factory automation.
Energy Management Systems
Used in smart meters and power monitoring where low power consumption is critical.
Factory Automation Controllers
Provides robust communication between PLCs and motor drives in electrically noisy environments.
Security and Surveillance
Facilitates long-distance control signals for PTZ cameras and access control panels.

Getting Started

To evaluate this part, ensure your PCB layout includes 0.1uF bypass capacitors close to the VCC pin and 120-ohm termination resistors at the cable ends. Note that this is a half-duplex device, so the DE and RE pins must be toggled to switch between transmit and receive modes.
