SN65HVD1781 

70V RS-485 transceiver with fail-safe

Explanation   These devices are designed for survival, such as direct short circuits leading to power overvoltage faults, miswiring failures, connector failures, cable crushing, and improper tool application. They also have powerful ESD events, with protection and high levels of human body model specifications. These devices combine a differential driver and a differential receiver, operating from a single power supply. In HVD1782, the differential output driver and the receiver's differential input are connected, forming an internal bus port for half-duplex (two-wire bus) communication. This port has a wide common-mode voltage range, enabling the device to operate at multiple points over long cable transmission routes.   Characteristics   Bus Pin Fault Protection: > ± 70 Five ('HVD1780,81) > ± 30 V ('HVD1782) Operates in the 3.3-V power supply range up to 5 V ± Protection of the 16 kV bus pin HBM Reduced load nodes by up to 320 units Fault protection receivers are open-circuited, short-circuited, and idle bus conditions Low power consumption Low standby current, maximum 1μA During the 4mm static operation of the Consumer Council The pins are compatible with industrial standard SN75176 115 kbps, with maximum signal rates of 1 Mbps and 10 Mbps Application HVAC network Secure electronics Building automation Telecommunications equipment Motion control Industrial networks
