ADUM161N1BRZ from Analog Devices, in a SOIC-16. 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	VDD1	power_in	Supply voltage for Isolator Side 1, specified over 1.7 V to 5.5 V in the recommended operating conditions.
2	VIA	input	Logic input A; an input pin on a side whose supply is unpowered must be held low to avoid powering the device through its ESD protection circuitry.
3	VIB	input	Logic input B; an input pin on a side whose supply is unpowered must be held low to avoid powering the device through its ESD protection circuitry.
4	VIC	input	Logic input C; an input pin on a side whose supply is unpowered must be held low to avoid powering the device through its ESD protection circuitry.
5	VID	input	Logic input D; an input pin on a side whose supply is unpowered must be held low to avoid powering the device through its ESD protection circuitry.
6	VIE	input	Logic input E; an input pin on a side whose supply is unpowered must be held low to avoid powering the device through its ESD protection circuitry.
7	VOF	output	Logic output F; it drives the channel F output state per the truth table, and goes to the fail-safe state (high for the N1 option) when the input-side supply is not applied.
8	GND1	power_in	Ground 1, the ground reference for Isolator Side 1.
9	GND2	power_in	Ground 2, the ground reference for Isolator Side 2.
10	VIF	input	Logic input F; an input pin on a side whose supply is unpowered must be held low to avoid powering the device through its ESD protection circuitry.
11	VOE	output	Logic output E; its state follows the truth table, and it goes to the fail-safe state (high for the N1 option) when the input-side supply is not applied.
12	VOD	output	Logic output D; its state follows the truth table, and it goes to the fail-safe state (high for the N1 option) when the input-side supply is not applied.
13	VOC	output	Logic output C; its state follows the truth table, and it goes to the fail-safe state (high for the N1 option) when the input-side supply is not applied.
14	VOB	output	Logic output B; its state follows the truth table, and it goes to the fail-safe state (high for the N1 option) when the input-side supply is not applied.
15	VOA	output	Logic output A; its state follows the truth table, and it goes to the fail-safe state (high for the N1 option) when the input-side supply is not applied.
16	VDD2	power_in	Supply voltage for Isolator Side 2, specified over 1.7 V to 5.5 V in the recommended operating conditions.
