Rev 1.00
July 28, 2011 16kV ESD Protected, +125В°C, 3.0V to 5.5V, TDFN Packaged, Low Power RS485/RS-422 Transmitter Features The Intersil ISL3298EMRTEP is a В±16.5kV HBM ESD Protected
(7kV IEC61000 contact), 3.0V to 5.5V powered, single
transmitter for balanced communication using the RS-485 and
RS-422 standards. This driver has very low bus currents
(±40mA), so it presents less than a “1/8 unit load” to the RS485 bus. This allows more than 256 transmitters on the
network without violating the RS-485 specification’s 32 unit
load maximum, and without using repeaters. Specifications per DLA VID V62/10602 Full Mil-Temp Electrical Performance from -55В°C to +125В°C Controlled Baseline with One Wafer Fabrication Site and One
Assembly/Test Site Full Homogeneous Lot Processing in Wafer Fab No Combination of Wafer Fabrication Lots in Assembly Full Traceability Through Assembly and Test by Date/Trace

-Class 3 ESD Level on all Other Pins .>8kV HBM Hot Plug circuitry ensures that the Tx outputs remain in a high
impedance state while the power supply stabilizes.
The driver on the ISL3298EMRTEP is not limited, so it can achieve
a 16Mbps data rate and is offered in the -55В°C to +125В°C
temperature range.
This devices also feature a logic supply pin (VL) that sets the
switching points of the DE and DI inputs to be compatible with
a lower supply voltage in mixed voltage systems.
