SN65HVD82DR

This device combines driver and receiver functions, offering robust durability to meet the stringent requirements of specific industrial applications. The bus pins are capable of withstanding ESD events and provide a high level of protection compliant with the Human Body Model, air-gap discharge, and contact discharge specifications. The device integrates a differential driver with a differential receiver, both powered by a single 5V supply. The driver differential output and receiver differential input are internally connected to form a bus port suitable for half-duplex (two-wire bus) communication. The wide common-mode voltage range makes the device suitable for multipoint applications over long cables. The device is rated for an operating temperature range of -40°C to 85°C. The SN65HVD82 device is a half - duplex RS - 485 transceiver suitable for data transmission at rates up to 250 kbps over controlled - impedance transmission media (such as twisted - pair cabling). The device features a high level of internal transient protection, making it able to withstand up ESD strikes up to 12 kV (per IEC 61000 - 4 - 2) and EFT transients up to 4 kV (per IEC 61000 - 4 - 4) without incurring damage. Up to 256 units of SN65HVD82 may share a common RS - 485 bus due to the device's low bus input currents. The device also features a low standby current consumption of 400 nA (typical).
