ISL3170EIUZ-T
Overview
The ISL3170EIUZ-T is a high-performance RS-485/RS-422 transceiver designed for robust serial communication using a 3.3V supply. It features advanced IEC61000-4-2 ESD protection on the bus pins and supports high data rates up to 20Mbps in a space-saving 10-lead MSOP package.
Why Choose This Part
This transceiver offers a high 1/8 unit load allowing up to 256 devices on a single bus, significantly expanding network capacity. It provides full fail-safe protection for open, shorted, or terminated/floating inputs and features hot-plug capability to prevent bus disruptions during power-up.
Applications
Getting Started
When designing your PCB, place a 0.1uF decoupling capacitor close to the VCC pin and ensure termination resistors (typically 120 ohms) are used at both ends of the bus. The part is fully compatible with standard UART signals from any 3.3V microcontroller like an STM32 or ESP32.
