SLLS877H – DECEMBER 2007 – REVISED MARCH 2017 SN65HVD178x Fault-Protected RS-485 Transceivers With 3.3-V to 5-V Operation
1 Features 3 Description The SN65HVD178x devices are designed to survive
overvoltage faults such as direct shorts to power
supplies, mis-wiring faults, connector failures, cable
crushes, and tool mis-applications. The devices are
also robust to ESD events with high levels of
protection to the human-body-model specification. 1 Bus-Pin Fault Protection to:
– > ±70 V (SN65HVD1780, SN65HVD1781)
– > ±30 V (SN65HVD1782)
Operation With 3.3-V to 5-V Supply Range
В±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
Low Power Consumption
– Low Standby Supply Current, 1 µA Maximum
– ICC 4-mA Quiescent Current During Operation …
