±16.5kV ESD Protected, +125°C, 3.0V to

5.5V, SOT-23/TDFN Packaged, Low Power,

RS-485/RS-422 Transmitters

Features

• 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

The Intersil ISL3293E, ISL3294E, ISL3295E, ISL3296E,

ISL3297E, ISL3298E are ±16.5kV HBM ESD Protected (7kV

IEC61000 contact), 3.0V to 5.5V powered, single

≤ 3.6V Only)

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

Systems (ISL3296E through ISL3298E Only)

transmitters for balanced communication using the RS-485

and RS-422 standards. These drivers have very low bus

currents (±40mA), so they present 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.

• Hot Plug - Tx Outputs Remain Three-state During

Power-up

• Low Tx Leakage Allows >256 Devices on the Bus

• High Data Rates. . . . . . . . . . . . . . . . . . . . . up to 20Mbps

Hot Plug circuitry ensures that the Tx outputs remain in a

high impedance state while the power supply stabilizes.

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

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

The ISL3293E, ISL3294E, ISL3296E, ISL3297E utilize slew

rate limited drivers which reduce EMI, and minimize reflections

from improperly terminated transmission lines, or from

unterminated stubs in multidrop and multipoint applications.

Drivers on the ISL3295E and ISL3298E are not limited, so they

can achieve the 20Mbps data rate. All versions are offered in

Industrial and Extended Industrial (-40°C to +125°C)

temperature ranges.

A 26% smaller footprint is available with the ISL3296E,

ISL3297E, ISL3298E’s TDFN package. These 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.

Applications

• Clock Distribution

• High Node Count Systems

• Space Constrained Systems

• Security Camera Networks

For companion single RS-485 receivers in micro packages,

please see the ISL3280E, ISL3281E, ISL3282E, ISL3283E,

ISL3284E data sheet.
