SN65HVD20 

Extended common-mode RS-485 transceiver

illustrate   Delivering performance far beyond typical RS-485 devices in HVD2x homes is a transceiver. In addition to meeting all the requirements of the TIA/EIA-485-A standard, the HVD2x family operates over an extended common-mode voltage range and features high ESD protection, wide receiver hysteresis, operation, and fault protection features. The devices are ideal for long-term cable networks, as well as applications such as ordinary transceivers where the environment is too harsh. These devices are twisted pair cables designed for multi-point bidirectional data transmission. Example applications are digital motor controllers, sensors and remote terminals, industrial process control, safety stations, and environmental control systems.   characteristic   The common mode voltage range (-20 V to 25 V) more than doubles the requirements for the TIA/EIA-485 Receiver Equalization Extended Cable Length, Signal Transmission Rate (HVD23, HVD24) Reduced unit load up to 256 nodes Bus I/O protection over 16 kV HBM Fault protection receiver open, short, and idle bus conditions Low standby current 1 -μA max Hysteresis receiver over 100 mV apply Long cable solutions Factory automation Secure networking Central air conditioning in the building Severe electromagnetic environment Power inverter Industrial transmission Avionics
