TISN65HVD1781DR
Overview
The SN65HVD1781DR is a robust half-duplex RS-485 transceiver designed to operate with supply voltages ranging from 3.15V to 5.5V. It is engineered for industrial environments, featuring high levels of protection against bus-pin faults and supporting data rates up to 1Mbps. The device is housed in an industry-standard 8-SOIC package and remains functional over a wide temperature range of -40C to 125C.
Why Choose This Part
This transceiver offers a low standby current of only 1uA and an active supply current between 3mA and 5mA, making it suitable for power-sensitive applications. It provides high fault protection on bus pins and includes 50mV of receiver hysteresis to improve noise immunity in industrial settings.
Applications
Key Specifications
Getting Started
Engineers can evaluate this part using a standard 8-pin SOIC breakout board or by integrating it into a prototype circuit with a 0.1uF decoupling capacitor. Ensure the driver enable (DE) and receiver enable (RE) pins are correctly logic-controlled by your MCU to manage the half-duplex bus direction.
