Overview

DATASHEET ISL3179E, ISL3180E High ESD Protected, 40Mbps, 3.3V, Full Fail-Safe RS-485/RS-422 Transceivers The ISL3179E and ISL3180E are high ESD protected (see Table 2 on page 2), 3.3V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication.

Each device has low bus currents (+220µA/-150µA), so they present a “1/5 unit load” to the RS-485 bus.

This allows up to 160 transceivers on the network without violating the RS-485 specification’s 32 unit load maximum, and without using repeaters.

Key Features

  • High ESD protection on RS-485 I/O pins - ISL3179E.

  • >9kV.
  • Specified for +125°C operation (ISL3179EF Only).
  • High data rates.
  • . . up to 40Mbps.
  • 5V tolerant logic inputs.
  • 1/5 unit load allows up to 160 devices on the bus.
