DESCRIPTION

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).

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.
