SLLSE83F – APRIL 2013 – REVISED JANUARY 2015
ISO71xxCC 4242-V
PK
Small-Footprint Low-Power Triple and Quad Channels Digital
Isolators
1 Features

3 Description
ISO7131, ISO7140, and ISO7141 devices provide
galvanic isolation up to 2500 V
RMS
for 1 minute per
UL and 4242 V
PK
per VDE. ISO7131 has three
channels with two forward and one reverse-direction
channels. ISO7140 and ISO7141 are quad-channel
isolators; ISO7140 has four forward channels,
ISO7141 has three forward and one reverse-direction
channels. These devices are capable of 50-Mbps
maximum data rate with 5-V supplies and 40-Mbps
maximum data rate with 3.3-V or 2.7-V supplies, with
integrated filters on the inputs for noise-prone
applications. The suffix F indicates that default output
state is low; otherwise, the default output state is high
(see
Table 3).
Each isolation channel has a logic input and output
buffer separated by a silicon dioxide (SiO
2
) insulation
barrier. Used with isolated power supplies, these
devices prevent noise currents on a data bus or other
circuits from entering the local ground and interfering
with or damaging sensitive circuitry. The devices
have TTL input thresholds and can operate from 2.7-
V, 3.3-V, and 5-V supplies. All inputs are 5-V tolerant
when supplied from a 2.7-V or 3.3-V supply.
