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
device also features a logic supply pin (V_L) that sets the V_OH 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.
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
provided on our website.
