These devices are half-duplex transceivers designed for RS-485 data bus networks. Powered by a 5-V supply, they are fully compliant with TIA/EIA-485A standard. With controlled transition times, these devices are suitable for transmitting data over long twisted-pair cables. SN65HVD3082E and SN75HVD3082E devices are optimized for signaling rates up to 200 kbps. SN65HVD3085E is suitable for data transmission up to 1 Mbps, whereas SN65HVD3088E is suitable for applications requiring signaling rates up to 20 Mbps. These devices are designed to operate with very low supply current, typically 0.3 mA, exclusive of the load. When in the inactive shutdown mode, the supply current drops to a few nanoamps, making these devices ideal for power-sensitive applications.
