DATASHEET
±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.

NAME FUNCTION
1 DI Driver input. A low on DI forces output Y low and
output Z high. Similarly, a high on DI forces
output Y high and output Z low.
2V
CC
System power supply input (1.8V to 3.6V).
3 DE Driver output enable. The driver outputs, Y and
Z, are enabled by bringing DE high, and are high
impedance when DE is low. If the driver enable
function is not needed, connect DE to V
CC
through a 1kΩ to 2kΩ resistor.
4 Z ±16.5kV HBM, ±7kV IEC61000 (contact

NOTES:
1. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte
tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil
Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
2. Please refer to TB347
for details on reel specifications.
3. For Moisture Sensitivity Level (MSL), please see device information page for ISL32613E
, ISL32614E. For more information on MSL please see
techbrief TB363
