Overview

DATASHEET ISL8485, ISL8490, ISL8491 5V, Low Power, High Speed, RS-485/RS-422 Transceivers The ISL8485, ISL8490, and ISL8491 RS-485/RS-422 devices are BiCMOS 5V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication.

Unlike competitive devices, this family is specified for 10% tolerance supplies (4.5V to 5.5V).

The ISL8485, ISL8490, and ISL8491 feature data rates up to 5Mbps.

Key Features

  • Specified for 10% tolerance supplies.
  • Class 3 ESD protection (HBM) on all pins: 7kV.
  • High data rates: up to 5Mbps.
  • Single unit load allows up to 32 devices on the bus.
  • Low quiescent current: 500µA.
  • -7V to +12V common-mode input voltage range.
  • Three state Rx and Tx outputs (except ISL8490).
  • 30ns propagation delays, 5ns skew.
  • Full duplex and half duplex pinouts.
  • Operation from a single +5V supply (10% tolera.
