SN65HVD1795 RS-485 Transceiver

These 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. They are also robust to ESD events, with high levels of protection to human-body model specifications. These devices combine a differential driver and a differential receiver, which.
