DESCRIPTION
ISO7131, ISO7140, and ISO7141 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, ISO7141 has three forward and one reverse-
direction channels. These devices are capable of 50 Mbps maximum data rate with 5V supplies and 40Mbps
maximum data rate with 3.3V or 2.7V 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 1).
Each isolation channel has a logic input and output buffer separated by a silicon dioxide (SiO₂) insulation barrier.
Used in conjunction 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 5V tolerant when supplied
from a 2.7V or 3.3V supply.
