1. Describe

The ADM2484EBRWZ is an isolated data transceiver, ±15 kV ESD protection for high speed, half-duplex or full-duplex Communication over multipoint transmission lines. For half-duplex operation, the transmitter output and receiver input share the same transmission line. Transmitter output pin Y Externally linked to receiver input pin A and transmitter Output pin Z is linked externally to receiver input pin B. This device features an Analog Devices, Inc., iCoupler® technology combines a three-channel isolator, a three-state differential line driver, and a differential input receiver into a single pack. Differential transmitter output and receiver input functions electrostatic discharge circuit that provides protection up to ±15 kV using the Human Body Model (HBM). logical aspect The device can be powered from a 5 V or 3.3 V supply, The bus side requires an isolated 3.3 V supply. The device features current limiting and thermal shutdown to protect against output short circuits and in case the bus Competition can lead to excessive power consumption.
