ISL3280E - RS-485/RS-422 Receivers

General Description

Receiver output: If A - B  -50mV, RO is high; If A - B  -200mV, RO is low; RO = High if A and B are unconnected (floating) or shorted.

Receiver output enable.

RO is enabled when RE is high, or RE is low; RO is high impedance when RE is low, or RE is high.

Key Features

  • an active high Rx enable pin and the ISL3282E and ISL3283E include an active low enable pin. All versions are offered in Industrial and Extended Industrial (-40°C to +125°C) temperature ranges. A 26% smaller footprint is available with the ISL3282E TDFN package. These devices, plus the ISL3284E, also feature a logic supply pin (VL) that sets the VOH level of the RO output (and the switching points of the RE/RE input) to be compatible with another supply voltage in mixed voltage systems.

DATASHEET ISL3280E, ISL3281E, ISL3282E, ISL3283E, ISL3284E ±16.5kV ESD Protected, +125°C, 3.0V to 5.5V, SOT-23/TDFN Packaged, 20Mbps, Full Fail-safe, Low Power, RS-485/RS-422 Receivers FN6543 Rev 4.01 Mar 31, 2022 The ISL3280E, ISL3281E, ISL3282E, ISL3283E, and ISL3284E are ±16.5kV IEC61000 ESD Protected, 3.0V to 5.5V powered, single receivers that meet both the RS-485 and RS-422 standards for balanced communication. These receivers have very low bus currents (+125µA/-100µA), so they present a true “1/8 unit load” to the RS-485 bus. This allows up to 256 receivers on the network without violating the RS-485 specification’s 32 unit load maximum and without using repeaters.
