Download the ADM489A datasheet PDF (ADM488A included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for eia rs-485 transceivers.

Description

The ADM488A and ADM489A are low power, differential line transceivers suitable for communication on multipoint bus transmission lines.

They are intended for balanced data transmission and comply with both RS-485 and RS-422 standards of the Electronics Industries Association (EIA).

Features

  • Complies with ANSI TIA/EIA-485-A-1998 and ISO 8482: 1987(E) 250 kbps data rate ±4 kV HBM ESD protection on all pins Single 5 V ± 10% supply.
  • 7 V to +12 V bus common-mode range Connect up to 32 nodes on the bus Reduced slew rate for low EM interference Short-circuit protection 30 μA supply current.
