SN65HVD1781D Datasheet

RS-485 Interface IC


This SN65HVD1781D device is designed to survive overvoltage faults such as direct shorts to power supplies, mis-wiring faults,connector failures, cable crushes, and tool mis-applications. The internal current-limit circuits allow fault survivability without causing the high bus currents that otherwise might damage external components or power supplies. It is also robust to ESD events, with high levels of protection to the JEDEC or IEC human-body-model specification. SN65HVD1781D Features • Bus-Pin Fault Protection to > ±70 V• Operation With 3.3-V to 5-V Supply Range• ±16 kV HBM Protection on Bus Pins• Reduced Unit Load for up to 320 Nodes• Failsafe Receiver for Open-Circuit, Short-Circuit and Idle-Bus Conditions• Designed for RS-485 and RS-422 Networks
