ISO7640FM and ISO7641FM provide galvanic isolation up to 6 KVPK
for 1 minute per UL and VDE. These devices are also certified up to 5-KVRMS
Reinforced isolation at a working voltage of 400 VRMS per
standards EN/UL/CSA 60950-1 and 61010-1. ISO7640F and ISO7641F are
quad-channel isolators; ISO7640F
has four forward and ISO7641F has three forward and one
reverse-direction channels. Suffix F
indicates that output defaults to Low-state in fail-safe conditions. M-Grade devices are high-speed isolators capable of 150-Mbps
rate with fast propagation delays.
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 5-V tolerant when supplied from 3.3-V
or 2.7-V supplies.
