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

Feb 14, 2019
The ISL31470E, ISL31472E, ISL31475E, and ISL31478E are
fault protected, extended common-mode range differential
transceivers that exceed the RS-485 and RS-422 standards for
balanced communication. The RS-485 bus pins (driver outputs
and receiver inputs) are protected against overvoltages up to
±60V. Additionally, these transceivers operate in environments
with common-mode voltages up to ±15V (exceeds the RS-485
requirement), making this RS-485 family one of the more
robust on the market.
Transmitters 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.
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 VOL = 1V (to
ease the design of opto-coupled isolated interfaces).
Half duplex (Rx inputs and Tx outputs multiplexed together)
and full duplex pinouts are available. See Table 1 on page 3 for
key features and configurations by device number.
For an RS-485 family with a ±25V extended common-mode
range, see the ISL31490E datasheet.

NOTES:
1. See TB347 for details about reel specifications.
2. Pb-free PDIPs can be used for through-hole wave solder processing only. They are not intended for use in Reflow solder processing applications.
3. These Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte tin plate
plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Pb-free products are
MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
4. For Moisture Sensitivity Level (MSL), see the ISL31470E, ISL31472E, ISL31475E, and ISL31478E device pages. For more information about MSL, see
TB363.
