ADUM161N1BRZ

Analog Devices · Digital Isolators · SOIC-16

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.
