The SN65HVD1780D is a 70V fault-protected RS-485 Transceiver designed to survive overvoltage faults such as direct shorts to power supplies, miswiring faults, connector failures, cable crushes and tool mis-applications. This device is also robust to ESD events with high levels of protection to the human-body-model specification. The SN65HVD178x device combine a differential driver and a differential receiver, which operate from a single power supply. In the SN65HVD1782, the driver differential outputs and the receiver differential inputs are connected internally to form a bus port suitable for half-duplex (Two-Wire bus) communication. This port features a wide common-mode voltage range, making the devices suitable for multipoint applications over long cable runs.
● Bus-pin fault protection
● ±16kV 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
● Pin-compatible with industry-standard
● Green product and no Sb/Br
●This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
