Overview

DATASHEET ISL8487E, ISL81487L, ISL81487E ±15kV ESD Protected, 1/8 Unit Load, 5V, Low Power, High Speed or Slew Rate Limited RS-485/RS-422 Transceivers FN6051 Rev.8.00 Sep 20, 2018 The ISL8487E, ISL81487L, and ISL81487E RS-485/RS-422 devices are ESD protected, fractional unit load (UL), BiCMOS, 5V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication.

Each driver output/receiver input is protected against ±15kV ESD strikes without latch-up.

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

Key Features

  • higher slew rates. The receiver (Rx) inputs feature a “fail-safe if open” design, which ensures a logic high Rx output if Rx inputs are floating. The driver (Tx) outputs are short-circuit protected, even for voltages exceeding the power supply voltage. Additionally, on-chip thermal shutdown circuitry disables the Tx outputs to prevent damage if power dissipation becomes excessive. The half duplex devices multiplex the Rx inputs and Tx outputs to allow transceivers with Rx and Tx disable function.
