±16.5kV ESD Protected, +125°C, 1.8V to 3.6V,

Low Power, SOT-23, RS-485/RS-422 Transmitters

ISL32613E, ISL32614E

The Intersil ISL32613E and ISL32614E are ±16.5kV HBM ESD

Protected (7kV IEC61000 contact), 1.8V powered, single

transmitters for differential communication. These drivers

have very low bus currents (±40µA), so they present less than

a “1/8 unit load” to the 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 circuitry ensures that the Tx outputs remain in a high

impedance state while the power supply stabilizes.

Both ICs utilize slew rate limited drivers, which reduce EMI and

minimize reflections from improperly terminated transmission

lines or unterminated stubs in multidrop and multipoint

applications. The ISL32613E is more slew rate limited for data

rates up to 128kbps, while the less limited ISL32614E is

useful for data rates up to 256kbps.

For companion low power single RS-485 receivers, please see

the ISL32610E data sheet.
