SN65HVD1782 RS-485 Transceiver

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. The SN65HVD178x devices combine a differential driver and a.
