IEC61000-4-2 ESD Protection

±15kV Airgap discharge, ±8kV contact

discharge (half-duplex versions).

3.3V or 5V operation

Full Fail-Safe Rx

predictable performance

when bus faults occur.

Fractional Unit Load Rx

allows up to 256 devices on

the bus without expensive

repeaters.

Hot Plug Capability

prevents data

corruption during

power-up on an

active bus.

The ISL3261x single Tx/Rx RS-485/422 operate at the

industry’s lowest supply voltage, 1.8V, while drawing very little

power. Designers can easily meet strict power budgets for

battery and remote sensing applications.
