ISL32490E, ISL32492E, ISL32493E, ISL32495E, ISL32496E, ISL32498E
В±60V Fault Protected, 5V, RS-485/RS-422 Transceivers with В±25V CMR and ESD Protection
The ISL32490E, ISL32492E, ISL32493E, ISL32495E,
ISL32496E, ISL32498E are fault protected, 5V powered,
differential transceivers that exceed the RS-485 and RS-422
standards for balanced communication. The RS-485 transceiver
pins (driver outputs and receiver inputs) are fault protected up to
В±60V and are protected against В±16.5kV ESD strikes without
latch-up. Additionally, the extended Common Mode Range
(CMR) allows these transceivers to operate in environments with
common mode voltages up to В±25V (>2x the RS-485
requirement), making this fault protected RS-485 family one of
the most robust on the market.
Transmitters (Tx) deliver an exceptional 2.5V (typical)
differential output voltage into the RS-485 specified 54О© load.
This yields better noise immunity than standard RS-485 ICs, or
allows up to six 120О© terminations in star network topologies.
Receiver (Rx) inputs feature a “full fail-safe” design that ensures
a logic high Rx output if Rx inputs are floating, shorted, or on a
terminated but undriven (idle) bus. Rx outputs have high drive
levels; typically, 15mA at VOL = 1V (for opto-coupled, isolated
applications). …
