Rev 2.00
July 27, 2015 В±16.5kV ESD Protected, +125В°C, 1.8V to 3.6V, Low Power, SOT-23,
RS-485/RS-422 Transmitters
The Intersil ISL32613E and ISL32614E are В±16.5kV HBM ESD
Protected (7kV IEC61000 contact), 1.8V powered, single
transmitters for differential communication. These drivers
have very low bus currents (В±40ВµA), 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. Features Hot Plug circuitry ensures that the Tx outputs remain in a high
impedance state while the power supply stabilizes. Specified for +125В°C or full military temperature range 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. Low Tx leakage allows >256 devices on the bus For companion low power single RS-485 receivers, please see
the ISL32610E datasheet. Pb-Free (RoHS Compliant) Wide supply voltage range 1.8V to 3.6V Low quiescent supply current 80ВµA (max)
