The ISO7641FCDW is a quad-channel Digital Isolator provides galvanic isolation up to 4242VPK per VDE. This device has 4 channels, three of which operate in the forward direction and one of which operates in the reverse direction. The C-grade device is capable of up to 25Mbps data rates with low power consumption and integrated filters for noise-prone applications. Recommended for lower-speed applications where input noise pulses of less than 6ns duration must be suppressed or when low-power consumption is critical. 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, it prevents noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. The device has TTL input thresholds.
