Tudi SN65HVD3082EDGKR-TUDI

These devices are half-duplex transceivers designed specifically for RS-485 data bus networks. They operate from a 5V supply and are fully compliant with the TIA/EIA-485A standard. These devices feature controlled slew rates, making them suitable for data transmission over long twisted-pair cables. The SN65HVD3082E and SN75HVD3082E are optimized for signaling rates up to 200kbps. The SN65HVD3085E supports data rates up to 1Mbps. In the inactive shutdown mode, supply current drops to a few nanoamps, making these devices ideal for power-sensitive applications.

The wide common-mode range and high ESD protection ratings of these devices make them suitable for demanding applications such as energy metering networks, power inverters, status/command signals on telecom shelves, wired shelf interconnects, and industrial automation networks where noise immunity is critical. These devices are pin-compatible with the industry-standard SN75176 package. A power-on reset circuit keeps the outputs in a high-impedance state until the supply voltage has stabilized. Thermal shutdown protects the devices from damage under system fault conditions. The SN75HVD3082E is characterized for operation from 0°C to 70°C, while the SN65HVD308xE is characterized for operation from -40°C to 85°C.

Drop-in replacement for imported SN65HVD3082 in MSOP package.

The HVD3082/3085/3088 is a 5V-powered, half-duplex, low-power, low slew rate RS-485 transceiver that fully meets the TIA/EIA-485 standard. The SN65HVD3082E, SN75HVD3082E, SN65HVD3088E, and SN65HVD3085E each incorporate a driver and a receiver, both of which can be independently enabled and disabled. When both are disabled, the driver and receiver outputs are in a high-impedance state. With 1/8 unit load, up to 160 transceivers can be connected on the same communication bus. The slew-rate-limited driver significantly reduces EMI and reflections caused by improperly terminated cables, enabling error-free data transmission at rates up to 500kbps with transitions as fast as 40mb. The SN65HVD3082E, SN75HVD3082E, SN65HVD3088E, and SN65HVD3085E operate over a supply voltage range of 4.75V to 5.25V, and feature fail-safe protection, over-temperature protection, current-limiting protection, overvoltage protection, and hot-swap capable control inputs. These devices offer excellent ESD performance: ±15kV HBM, contact discharge per IEC61000-4-2 ±15kV.
