Rev 3.00
September 25, 2015 The Intersil ISL3293E, ISL3294E, ISL3295E, ISL3296E,
ISL3297E, ISL3298E are В±16.5kV HBM ESD Protected (7kV
IEC61000 contact), 3.0V to 5.5V powered, single transmitters
for balanced communication using the RS-485 and RS-422
standards. These drivers have very low bus currents (В±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. Features Hot Plug circuitry ensures that the Tx outputs remain in a high
impedance state while the power supply stabilizes. Hot plug -Tx outputs remain three-state during power-up 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 (-40В°C to +125В°C) temperature ranges. High data rates up to 20Mbps High ESD protection on RS-485 outputs В±16.5kV HBM
