SN65HVD485E
- Bus-pin ESD protection up to 15 kV
- 1/2 Unit load: up to 64 nodes on a bus
- Bus-open-failsafe receiver
- Glitch-free power-up and power-down bus inputs and outputs
- Available in small VSSOP-8 package
- Meets or exceeds the requirements of the TIA/EIA-485A standard
- Industry-standard SN75176 footprint
The SN65HVD485E device is a half-duplex transceiver designed for RS-485 data bus networks. Powered by a 5-V supply, it is fully compliant with the TIA/EIA-485A standard. This device is suitable for data transmission up to 10 Mbps over long twisted-pair cables and is designed to operate with very low supply current, typically less than 2 mA, exclusive of the load. When the device is in the inactive shutdown mode, the supply current drops below 1 mA.
The wide common-mode range and high ESD protection levels of this device make it suitable for demanding applications such as: electrical inverters, status/command signals across telecom racks, cabled chassis interconnects, and industrial automation networks where noise tolerance is essential. The SN65HVD485E device matches the industry-standard footprint of the SN75176 device. Power-on reset circuits keep the outputs in a high-impedance state until the supply voltage has stabilized. A thermal-shutdown function protects the device from damage due to system-fault conditions. The SN65HVD485E device is characterized for operation from –40°C to 85°C air temperature.

Modbus is an application protocol for serial data transmission that often uses RS-485 for serial data transfer. This reference design implements a gateway between Modbus and the Bluetooth® Smart CC2540 wireless MCU. It serves as a replacement for wires in an RS-485 network, and it allows another (...)
