Overview
The SN65HVD3082EP is a half-duplex RS-485 transceiver produced by Texas Instruments. This device is designed for use in RS-485 data bus networks and is fully compliant with the TIA/EIA-485A standard. It operates on a 5-V supply and is optimized for signaling rates up to 200 kbps, making it suitable for transmitting data over long twisted-pair cables. The SN65HVD3082EP is characterized by its low quiescent power consumption, with an active mode current of 0.3 mA and a shutdown mode current of just a few nanoamps, which is ideal for power-sensitive applications.
