±16.5kV ESD Protected, +125°C, 3.0V to 5.5V, TDFN

Packaged, 16Mbps, Full Fail-safe, Low Power,

RS-485/RS-422 Receiver

ISL3282EMRTEP

The Intersil ISL3282EMRTEP is a ±16.5kV IEC61000 ESD

protected, 3.0V to 5.5V powered, single receiver that meets both

the RS-485 and RS-422 standards for balanced communication.

This receiver has very low bus currents (+125µA/-100µA), so it

presents 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 ISL3282EMRTEP includes an active low enable pin and is

offered in the Military Temperature range (-55°C to +125°C).

A 26% smaller footprint is available with the TDFN package. This

of the RO output (and the switching points of the RE/RE input) to

be compatible with another supply voltage in mixed voltage

systems.

Device Information

The specifications for an Enhanced Product (EP) device are

defined in a Vendor Item Drawing (VID), which is controlled by the

Defense Supply Center in Columbus (DSCC). “Hot-links” to the

applicable VID and other supporting application information are
