The THVD1429DR from Texas Instruments is a half-duplex RS-485 transceiver featuring integrated surge protection. It meets or exceeds TIA/EIA-485A standards and operates within a wide supply voltage range of 3V to 5.5V.
This transceiver supports data rates up to 20 Mbps and offers an extended ambient temperature range of -40°C to 125°C. Key electrical features include ±12V extended operational common-mode range and 30 mV receiver hysteresis for enhanced noise rejection. It also boasts low power consumption, with standby supply current less than 2 µA.
The THVD1429DR is designed for robust performance, incorporating ±16 kV HBM ESD protection and various IEC 61000-4-2 and IEC 61000-4-4 surge protection levels. It includes failsafe features for open, short, and idle bus conditions and supports up to 256 bus nodes with its 1/8 unit load capability.
Packaged in an industry-standard 8-pin SOIC package, the THVD1429DR is suitable for surface mount applications. Its glitch-free power-up/down capability makes it ideal for hot-plugging scenarios.
