ADUM7441CRQZ-RL7 from Analog Devices, in a QSOP-16-150mil. 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 VDD1A power_in Supply Voltage A for Isolator Side 1, 3.0 V to 5.5 V; must be connected externally to pin 7 and bypassed with a 0.01 µF to 0.1 µF ceramic capacitor to GND1 (pin 2).
2 GND1 power_in Ground 1, the ground reference for Isolator Side 1; internally connected to pin 8, and connecting both to GND1 is recommended.
3 VIA input Logic Input A for Isolator Side 1.
4 VIB input Logic Input B for Isolator Side 1.
5 VIC input Logic Input C for Isolator Side 1.
6 VOD output Logic Output D on Isolator Side 2; the output is in the default high state when the input side is unpowered.
7 VDD1B power_in Supply Voltage B for Isolator Side 1, 3.0 V to 5.5 V; must be connected externally to pin 1 and bypassed with a 0.01 µF to 0.1 µF ceramic capacitor to GND1 (pin 8).
8 GND1 power_in Ground 1, the ground reference for Isolator Side 1; internally connected to pin 2, and connecting both to GND1 is recommended.
9 GND2 power_in Ground 2, the ground reference for Isolator Side 2; internally connected to pin 15, and connecting both to GND2 is recommended.
10 VDD2B power_in Supply Voltage B for Isolator Side 2, 3.0 V to 5.5 V; must be connected externally to pin 16 and bypassed with a 0.01 µF to 0.1 µF ceramic capacitor to GND2 (pin 9).
11 VID input Logic Input D for Isolator Side 1.
12 VOC output Logic Output C on Isolator Side 2.
13 VOB output Logic Output B on Isolator Side 2.
14 VOA output Logic Output A on Isolator Side 2.
15 GND2 power_in Ground 2, the ground reference for Isolator Side 2; internally connected to pin 9, and connecting both to GND2 is recommended.
16 VDD2A power_in Supply Voltage A for Isolator Side 2, 3.0 V to 5.5 V; must be connected externally to pin 10 and bypassed with a 0.01 µF to 0.1 µF ceramic capacitor to GND2 (pin 15).
