±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

PublishTime：2019-05-24

The Intersil ISL3280E, ISL3281E, ISL3282E, ISL3283E,

ISL3284E, ISL3285E 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.

Receiver inputs feature a “Full Fail-Safe” design, which ensures

a logic high Rx output if Rx inputs are floating, shorted, or

terminated but undriven.

The ISL3280E and ISL3284E feature an always enabled Rx;

the ISL3281E and ISL3285E feature 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 and

ISL3285E 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.

For companion single RS-485 transmitters in micro packages,

please see the ISL3293E datasheet.
