Description

The SN65HVD74DR is a robust, high-speed differential line transceiver designed for RS-485 communication networks. It supports half-duplex operation, meaning it can either transmit or receive data, but not both simultaneously. This transceiver operates over a wide voltage range from 3.3V to 5V, making it versatile for various applications. It features a data rate of up to 25 Mbps, enabling fast data transmission.
The SN65HVD74DR includes fail-safe circuitry, which ensures a stable logic output in the presence of an open circuit, short circuit, or idle bus conditions, enhancing reliability. It also has thermal shutdown protection and current limiting to prevent device damage under fault conditions. The device comes in an SOIC (Small Outline Integrated Circuit) package, which is compact and suitable for space-constrained designs.
With excellent performance in noise-prone environments and compliance with the RS-485 standard, the SN65HVD74DR is ideal for industrial automation, building automation systems, and other applications requiring reliable data communication over long distances.
