描述
The MAX22_2_ are a family of 2-channel reinforced ultra-low-power digital isolators. The MAX22_2_ consume ultra-low power not only in DC but also across the entire operating speed range up to 10Mbps. The family offers two unidirectional channel configurations to accommodate any 2-channel design.
The MAX22_20 feature two channels transferring digital signals in one direction. The MAX22_21 have one channel to transmit data in one direction and the other channel to transmit in the opposite direction.
The MAX22420/1 are available in an 8-pin narrow-body SOIC package with 4mm creepage and clearance and are rated up to 3kVRMS. The MAX22820/1 are available in an 8-pin wide-body SOIC package with 8mm creepage and clearance and are rated up to 5kVRMS. This family of digital isolators offers ultra-low-power operation, high electromagnetic interference (EMI) immunity, and stable temperature performance through Analog Devices’ proprietary process technology. The devices isolate different ground domains and block high-voltage/high-current transients from sensitive or human interface circuitry.
The family of devices has a maximum data rate of 10Mbps and can be ordered with two glitch filter options and default-high or default-low outputs. The default is the state the output assumes when the input is open circuit. The B/E versions have 70ns (typ) glitch filter and C/F versions have 29ns (typ) glitch filter. The devices have two supply inputs (VDDA and VDDB) that independently set the logic levels on either side of device. VDDA and VDDB are referenced to GNDA and GNDB, respectively. The family also features a refresh circuit to ensure output accuracy when an input remains in the same state indefinitely.
