RS-485 и RS-422 SN75HVD3082ED

Драйвер приемопередатчика RS485 , 4.5В-5.5В, SOIC-8

The SN75HVD3082ED is a low-power Half-duplex Transceiver designed for RS-485 data bus networks. Powered by a 5V supply, it is fully compliant with TIA/EIA-485A standard. With controlled transition times, this device is suitable for transmitting data over long twisted-pair cables. It is optimized for signalling rate up to 200kbps. This device is designed to operate with very low supply current, typically 0.3mA, exclusive of the load. When in the inactive-shutdown mode, the supply current drops to a few nanoamps, which makes these devices ideal for power-sensitive applications. The wide common-mode range and high ESD-protection levels of these devices makes them suitable for demanding applications such as energy meter networks, electrical inverters, status and command signals across telecom racks, cabled chassis interconnects and industrial automation networks where noise tolerance is essential.

• Failsafe receiver (bus open, bus shorted and bus idle)
• Glitch-free power-up and power-down bus inputs and outputs
• Low quiescent power - 0.3mA Active mode and 1nA shutdown mode
• 1/8 Unit-load (up to 256 nodes on the bus)
• Bus-pin ESD protection up to 15kV
• Green product and no Sb/Br
