DESCRIPTION
ISO7631F, ISO7640F and ISO7641F provide galvanic isolation up to 4 KVPK per VDE. ISO7631F has 3 channels
with two forward and one reverse direction channels. 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 whereas C-Grade devices can run up to 25
Mbps data rate with low power consumption and integrated filters for noise-prone applications. C-Grade devices
are recommended for lower speed applications where input noise pulses of less than 6 ns duration need to be
suppressed or lower power consumption is critical.
