ADUM5241ARZ-RL7

Analog Devices · Digital Isolators · SOP-8

ADUM5241ARZ-RL7 from Analog Devices, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD power_in Supply voltage for the isolator primary side, 4.5 V to 5.5 V with the DC-to-DC converter enabled and 2.7 V to 4.0 V with the DC-to-DC converter disabled.
2 VOA output Logic Output A; the datasheet specifies its logic-high level as (VDD or VISO) minus 0.1 V to 0.5 V at IOx = −20 µA to −4 mA and its logic-low level as 0.1 V typical at 20 µA and 0.4 V maximum at 4 mA.
3 VIB input Logic Input B; the logic-high threshold is at least 0.7 × (VDD or VISO) and the logic-low threshold is at most 0.3 × (VDD or VISO), with input current limited to ±10 µA.
4 GND power_in Ground reference for the isolator primary side; the datasheet recommends enlarged pads with multiple vias to the ground plane to conduct heat away from the device.
5 GNDISO power_in Isolated ground, the ground reference for the isolator secondary side.
6 VOB output Logic Output B; the datasheet specifies its logic-high level as (VDD or VISO) minus 0.1 V to 0.5 V at IOx = −20 µA to −4 mA and its logic-low level as 0.1 V typical at 20 µA and 0.4 V maximum at 4 mA.
7 VIA input Logic Input A; the logic-high threshold is at least 0.7 × (VDD or VISO) and the logic-low threshold is at most 0.3 × (VDD or VISO), with input current limited to ±10 µA.
8 VISO power_out Isolated supply voltage for the isolator secondary side, 4.5 V to 5.5 V output when the DC-to-DC converter is enabled and 2.7 V to 5.5 V input when it is disabled.
