±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 datasheet.

NOTES:
7. All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless otherwise specified.
8. Applies to peak current. See “Typical Performance Curves” on page 8 for more information.
9. If the Driver Enable function is not needed, connect DE to VCC through a 1kΩ to 2kΩ resistor.
10. Compliance to data sheet limits is assured by one or more methods: production test, characterization and/or design.
