DATASHEET 16.5kV ESD Protected, 16Mbps, with Active Low Rx EN, RS-485/422 Receiver ISL3282EMRTEP Features The Intersil ISL3282EMRTEP is a 16.5kV IEC61000 ESD Specifications per DSCC VID V62/10601-01XB protected, 3.0V to 5.5V powered, single receiver that meets Full military temperature electrical performance from both the RS-485 and RS-422 standards for balanced -55C to +125C communication. This receiver has very low bus currents Controlled baseline with one wafer fabrication site and one (+125A/-100A), so it presents a true 1/8 unit load to the assembly/test site RS-485 bus. This allows up to 256 receivers on the network without violating the RS-485 specifications 32 unit load Full homogeneous lot processing in wafer fab maximum and without using repeaters. No combination of wafer fabrication lots in assembly Receiver inputs feature a Full Fail-Safe design, which ensures Full traceability through assembly and test by date/trace a logic high Rx output if Rx inputs are floating, shorted, or code assignment terminated but undriven. Enhanced process change notification The ISL3282EMRTEP includes an active low enable pin and is Enhanced obsolescence management offered in the Military Temperature range (-55C to +125C). Eliminates need for up-screening a COTS component A 26% smaller footprint is available with the TDFN package. 16.5kV IEC61000 ESD protection on RS-485 inputs This device also features a logic supply pin (V ) that sets the L V level of the RO output (and the switching points of the Class 3 ESD level on all other pins >5kV HBM OH RE/RE input) to be compatible with another supply voltage in Wide supply range . 3.0V to 5.5V mixed voltage systems. Specified for +125C operation Logic supply pin (V ) eases operation in mixed supply Device Information L systems The specifications for an Enhanced Product (EP) device are Full fail-safe (open, short, terminated/undriven) defined in a Vendor Item Drawing (VID), which is controlled by the Defense Supply Center in Columbus (DSCC). Hot-links to True 1/8 unit load allows up to 256 devices on the bus the applicable VID and other supporting application High data rates up to 16Mbps information are provided on our website. Low quiescent supply current 500A (maximum) Applications Very low shutdown supply current . 20A (maximum) Clock distribution -7V to +12V common-mode input voltage range High node count systems Tri-statable Rx available (active low or high EN input) Space constrained systems 5V tolerant logic inputs when V 5V CC Security camera networks Building environmental control/lighting systems Industrial/process control networks TABLE 1.
