ADM488 - EIA RS-485 Transceivers

Description

The ADM488 and ADM489 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 Electronics Industries Association (EIA) RS-485 and RS-422 standards.

Features

  • Meets EIA RS-485 and RS-422 standards 250 kbps data rate Single 5 V ± 10% supply.
  • 7 V to +12 V bus common-mode range 12 kΩ input impedance 2 kV EFT protection meets IEC1000-4-4 High EM immunity meets IEC1000-4-3 Reduced slew rate for low EM interference Short-circuit protection Excellent noise immunity 30 μA supply current.
