ADM2487EBRWZ

数字隔离器 2.5kV Sgnl Iso Full/Half Duplex

2.5 kV Isolated RS-485 Transceivers with  Integrated Transformer Driver

GENERAL DESCRIPTION ADM2487EBRWZ

The ADM2482E/ADM2487E are isolated data transceivers with  ±15 kV ESD protection and are suitable for high speed, halfduplex  or full-duplex communication on multipoint transmission  lines. For half-duplex operation, the transmitter outputs and  receiver inputs share the same transmission line. Transmitter  Output Pin Y is linked externally to Receiver Input Pin A, and  Transmitter Output Pin Z to Receiver Input Pin B. The parts are  designed for balanced transmission lines and comply with  TIA/EIA-485-A-98 and ISO 8482:1987(E).
