±60V Fault Protected, 5V, RS-485/RS-422 Transceivers

with ±25V CMR and ESD Protection

ISL32490E, ISL32492E, ISL32493E, ISL32495E, ISL32496E,

ISL32498E

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

±60V and are protected against ±16.5kV ESD strikes without

latch-up. Additionally, the extended common mode range allows

these transceivers to operate in environments with common

mode voltages up to ±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 54Ω load.

This yields better noise immunity than standard RS-485 ICs or

allows up to six 120Ω 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 @ V

isolated applications).

Half duplex (Rx inputs and Tx outputs multiplexed together)

and full duplex pinouts are available. See Table 1 on page 2 for

key features and configurations by device number.

For fault protected or wide common mode range RS-485

transceivers with cable invert (polarity reversal) pins, please
