Overview
The SN65HVD05DR, produced by Texas Instruments, is a high-output RS-485 transceiver designed for balanced data transmission. This device combines a 3-state differential line driver and a differential line receiver, making it suitable for various industrial and commercial applications. It is electrically compatible with ANSI TIA/EIA-485-A and ISO 8482E standards, ensuring interoperability with other standard-compliant devices. The SN65HVD05DR features glitch-free power-up and power-down protection, which is crucial for hot-plugging applications, and it operates over a wide temperature range from -40°C to 85°C.
