TITHVD1410DR
Overview
The THVD1410DR is a robust, low-power half-duplex RS-485 transceiver designed for industrial applications requiring data rates up to 500 kbps. It operates from a wide supply range of 3V to 5.5V and features an extended common-mode voltage range of +/-15V for reliable operation in electrically noisy environments. The device includes integrated bus I/O ESD protection and support for up to 256 bus nodes on a single network.
Why Choose This Part
This transceiver offers a high level of integration with failsafe circuitry for open, shorted, and idle bus conditions, preventing undefined receiver states. Its 500 kbps data rate is optimized for low electromagnetic interference (EMI), while the large 30 mV receiver hysteresis ensures robust noise rejection. The ultra-low 1 uA standby current makes it suitable for power-sensitive remote terminal units.

Key Specifications
Getting Started
To evaluate this part, use a standard 8-pin SOIC breakout board or integrate it into a bus topology with 120-ohm termination resistors at the end nodes. Ensure the DE and /RE pins are correctly toggled by your microcontroller for half-duplex flow control. For 5V systems, the device provides higher differential drive strength suitable for PROFIBUS compliance.
