16kV ESD Protected, +125°C, 3.0V to 5.5V, TDFN

Packaged, Low Power RS-485/RS-422 Transmitter

ISL3298EMRTEP

Features

The Intersil ISL3298EMRTEP is a ±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 RS-485 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 -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

• Full Traceability Through Assembly and Test by Date/Trace

Code Assignment

Hot Plug circuitry ensures that the Tx outputs remain in a high

impedance state while the power supply stabilizes.

• Enhanced Process Change Notification

• Enhanced Obsolescence Management

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.

• Eliminates Need for Up-Screening a COTS Component

• High ESD Protection on RS-485 Outputs . . . . ±16.5kV HBM

- IEC61000-4-2 Contact Test Method. . . . . . . . . . . . . . . ±7kV

- Class 3 ESD Level on all Other Pins. . . . . . . . . . .>8kV HBM

This devices also feature a logic supply pin (V ) that sets the

switching points of the DE and DI inputs to be compatible with a

lower supply voltage in mixed voltage systems.

• Specified for +125°C Operation (V ≤ 3.6V Only)

• Logic Supply Pin (V ) Eases Operation in Mixed Supply Systems

For a companion single RS-485 receiver in micro packages,

please see the ISL3282EMRTEP data sheet.

• Hot Plug - Tx Output Remains Three-state During Power-up

• Low Tx Leakage Allows >256 Devices on the Bus

Applications

• Clock Distribution

• High Data Rates . . . . . . . . . . . . . . . . . . . . . . . . . up to 16Mbps

• Low Quiescent Supply Current . . . . . . . . . . . . . . .150µA (Max)

- Very Low Shutdown Supply Current. . . . . . . . . . 1µA (Max)

• High Node Count Systems

• Space Constrained Systems

• Security Camera Networks

• Building Environmental Control/Lighting Systems

• Industrial/Process Control Networks

• -7V to +12V Common Mode Output Voltage Range (V ≤ 3.6V

Only)

• Current Limiting and Thermal Shutdown for Driver Overload

Protection (V ≤ 3.6V Only)

• Tri-statable Tx Output

• 5V Tolerant Logic Input When V ≤5V
