Fault Protected, Extended Common-Mode Range, RS-485/RS-422 Transceivers

with ±16.5kV ESD

FN7784

Rev 2.00

Feb 14, 2019

The ISL32470E, ISL32472E, ISL32475E, and ISL32478E are

Features

fault-protected, extended common-mode range differential

• Fault protected RS-485 bus pins . . . . . . . . . . . . . . Up to ±60V

transceivers that exceed the RS-485 and RS-422 standards for

balanced communication. The RS-485 bus pins (driver outputs

and receiver inputs) are fault protected against overvoltages

up to ±60V and are protected against ±16.5kV ESD strikes

without latch-up. Additionally, these transceivers operate in

environments with common-mode voltages up to ±15V

(exceeds the RS-485 requirement), making this fault-protected

RS-485 family one of the most robust on the market.

• Extended common-mode range. . . . . . . . . . . . . . . . . . . . ±15V

larger than required for RS-485

• 1/4 unit load for up to 128 devices on the bus

• ±16.5kV HBM ESD protection on RS-485 bus pins

• High transient over-voltage tolerance . . . . . . . . . . . . . . . ±80V

• Full fail-safe (open, short, terminated) RS-485 receivers

The 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 topologies.

• High Rx I for opto-couplers in isolated designs

• Hot plug circuitry: Tx and Rx outputs remain three-state

during power-up/power-down

• RS-485 data rates. . . . . . . . . . . . . . . . . . . . . .250kbps to 15Mbps

• Low quiescent supply current. . . . . . . . . . . . . . . . . . . . 2.3mA

• Ultra low shutdown supply current. . . . . . . . . . . . . . . . . . 10µA

The receiver (Rx) inputs feature a full fail-safe design that

ensures a logic high Rx output if the Rx inputs are floating,

shorted, or on a terminated but undriven (idle) bus. The Rx

outputs feature high drive levels; typically, 15mA at V = 1V

(to ease the design of opto-coupled isolated interfaces).

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.

• Utility meters and automated meter reading systems

• High node count RS-485 systems

• PROFIBUS and RS-485 based field bus networks, factory

automation

For a fault-protected RS-485 transceiver with a ±25V extended

common-mode range, see the ISL32490E and ISL32483E

datasheets.

• Security camera networks

• Building lighting and environmental control systems

• Industrial/process control networks
