DESCRIPTION
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 end equipment
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 (see Table 1). M-Grade devices are high speed isolators
capable of 150 Mbps data rate with fast propagation delays
