SN65HVD485EDG4 Datasheet PDF - TI

●The SN65HVD485EDG4 is a half-duplex Transceiver designed for RS-485 data bus networks. Powered by a 5V supply, it is fully compliant with the TIA/EIA-485A standard. This device is suitable for data transmission up to 10Mbps over long twisted-pair cables and is designed to operate with very low supply current, typically less than 2mA, exclusive of the load. When the device is in the in-active shutdown mode, the supply current drops below 1mA. 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. 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.

● Bus-open-failsafe receiver

● Glitch-free power-up and power-down bus inputs and outputs

● Meets or exceeds the requirements of the TIA/EIA-485A standard

● Industry-standard SN75176 footprint

● Bus-pin ESD protection up to 15kV

● 1/2 Unit-load (up to 64 nodes on the bus)

● Green product and no Sb/Br

●Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
