Product Overview
The SN65HVD3082EDR is a Texas Instruments low-power RS-485 transceiver for Signal_Chain designs using RS-485 data bus networks. It meets or exceeds TIA/EIA-485A and uses a half-duplex transceiver topology. The bus interface supports 1/8 unit load operation, allowing up to 256 nodes on the bus, with a maximum signaling rate of up to 200 kbps for the SN65HVD3082E and SN75HVD3082E devices.
Power operation is based on a nominal 5 V supply, with a recommended VCC range of 4.5 V to 5.5 V. The device specifies 0.3 mA typical active supply current excluding load and 1 nA shutdown supply current in inactive-shutdown mode. Recommended bus terminal voltage is -7 V to 12 V, and recommended differential input voltage is -12 V to 12 V.
The part is supplied in an SOIC (D, 8), 4.9 mm x 6 mm package. Pin functions include R receive data output, active-low RE, active-high DE, D driver input, GND, A and B differential bus terminals, and VCC. Protection and operating limits include bus-pin ESD protection up to 15 kV, electrical fast transient rating of ±4000 V on A, B, and GND, and D-package operating free-air temperature from -40 °C to 105 °C.
