ADIADM485JRZ-REEL
Overview
The ADM485JRZ-REEL is a differential line transceiver designed for high-speed, half-duplex RS-485 and RS-422 communication. Operating from a 5V supply, it supports data rates up to 5Mbps and integrates thermal shutdown and short-circuit protection to ensure robust operation in industrial environments. The device features a low-power design, drawing as little as 1mA when the outputs are disabled.
Why Choose This Part
This transceiver provides a high data rate of 5Mbps while maintaining low power consumption of 2.2mA during active operation. It includes a fail-safe receiver design to ensure a logic high state when inputs are open-circuited and protects the bus with High-Z outputs during power-off conditions.
Applications
Key Specifications
Getting Started
To implement this part, connect the DI (Driver Input) and RO (Receiver Output) to your microcontroller's UART and use the DE/RE pins to control the bus direction. Ensure a 120-ohm termination resistor is placed at both ends of the bus and include a 0.1uF ceramic decoupling capacitor close to the VCC pin (4.75V to 5.25V range).
