SN65HVD1780D .

产品概述

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
