The ISL3298EMRTEP is a ±16.5kV HBM ESD Protected (7kV
Features
IEC61000 contact), 3.0V to 5.5V powered, single transmitter
• Specifications per DLA VID V62/10602
for balanced communication using the RS-485 and RS-422
standards. This driver has very low bus currents (±40mA);
therefore, it presents less than a 1/8 unit load to the RS-485
bus. This allows more than 256 transmitters on the network
without violating the RS-485 specification 32 unit load
maximum, and without using repeaters.
• Full mil-temp electrical performance from -55°C to +125°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
Hot Plug circuitry ensures that the Tx outputs remain in a high
impedance state while the power supply stabilizes.
• Full traceability through assembly and test by date/trace
code assignment
• Enhanced process change notification
The driver on the ISL3298EMRTEP is not limited, so it can achieve
a 16Mbps data rate and is offered in the -55°C to +125°C
temperature range.
• Enhanced obsolescence management
• Eliminates need for up-screening a COTS component
• High ESD protection on RS-485 outputs ±16.5kV HBM

This devices also feature a logic supply pin (V ) that sets the
L
switching points of the DE and DI inputs to be compatible with
a lower supply voltage in mixed voltage systems.
For a companion single RS-485 receiver in micro packages,
see the ISL3282EMRTEP datasheet.
