The SN65HVD485EDR is a half-duplex RS-485 transceiver from Texas Instruments. It is an integrated circuit for transmission and reception of balanced data signals in multipoint systems. With a very low power dissipation of 600 µA, it is the perfect choice for many embedded systems, waveform audio, industrial control, POS systems, energy management, and automotive applications. The SN65HVD485EDR is able to handle data rates up to 10 Mbps, up to 32 transceivers, and 2.1 kV ESD protection. It features hot swap protection, which helps prevent transmission errors or data corruption during a node addition or removal. Additionally, it features an automatic data direction control and supports 5 V and 3.3 V powered systems. It also has Built in diagnostics and error reporting that helps system designers detect and repair data system problems quickly.
