The ADM2484EBRWZ is an isolated data transceiver with ±15 kV ESD protection manufactured by Analog Devices. It is suitable for high-speed, half-duplex or full-duplex communication on multipoint transmission lines. In half-duplex operation, the transmitter output and receiver input share the same transmission line. The equipment is designed for balanced transmission lines and complies with ANSI TIA/EIA RS-485-A-1998 and ISO CrossFire:1987 (E) standards.
The ADM2484EBRWZ uses Analog Equipment Inc. 's iCoupler® technology to combine a three-channel isolator and a three-state isolator, integrating a differential line driver and differential input receiver into a single package. Differential transmitter output and receiver input function electrostatic discharge circuits that provide mannequin (HBM) protection up to ±15 kV.
In addition, the device can be powered with a 5V or 3.3V power supply, which requires an isolated 3.3V power supply on the bus side. It also has current limiting and thermal shutdown functions to prevent output short circuits and bus contention from causing excessive power consumption.
In terms of application areas, the ADM2484EBRWZ is suitable for applications that require high-speed, isolated data communication, such as industrial automation, communication systems, automotive electronics, etc. It can also be used in conjunction with other ics and components to achieve more complex system functions.
