SLLSEC3F – SEPTEMBER 2012 – REVISED APRIL 2016 ISO76x1 Low-Power Triple and Quad-Channels Digital Isolators
1 Features 3 Description The ISO7631F and ISO7641F devices provide
galvanic isolation up to 4242 VPK per VDE. The
ISO7631F device has three channels, two of which
operate in the forward direction and one which
operates in the reverse direction. The ISO7641F
device has 4 channels, three of which operate in the
forward direction and one of which operates in the
reverse direction. Suffix F indicates that output
defaults to low-state in fail-safe conditions (see ). MGrade devices are high-speed isolators capable of up
to150-Mbps data rates with fast propagation delays,
whereas C-Grade devices are capable of up to 25Mbps data rates with low power consumption and
integrated filters for noise-prone applications. CGrade devices are recommended for lower-speed
applications where input noise pulses of less than 6
ns duration must be suppressed, or when low-power
consumption is critical. 1 Signaling Rate: 150 Mbps (M-Grade), 25 Mbps
(C-Grade) …
