π220N61Q

2Pai Semi · I2C Isolators · SOIC-16-300mil

π220N61Q from 2Pai Semi, in a SOIC-16-300mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND1 power_in Side-1 reference ground. Return for VDD1 and the side-1 SDA1/SCL1 signals.
2 NC unconnected No internal connection. Leave floating or tie to GND1.
3 VDD1 power_in Isolator side-1 supply voltage. Operating range 3.0 V to 5.5 V; bypass to GND1 with a local decoupling capacitor (typ. 0.1 µF).
4 NC unconnected No internal connection.
5 SDA1 bidirectional Side-1 I2C serial data line. Open-drain bidirectional; requires external pull-up to VDD1. Sink capability up to 3.5 mA (VOL1 ≤ 0.8 V).
6 SCL1 bidirectional Side-1 I2C serial clock line. Open-drain bidirectional; requires external pull-up to VDD1. Supports up to 2 MHz operation.
7 GND1 power_in Side-1 reference ground (internally tied to pins 1 and 8).
8 GND1 power_in Side-1 reference ground (internally tied to pins 1 and 7).
9 GND2 power_in Side-2 reference ground. Return for VDD2 and the side-2 SDA2/SCL2 signals.
10 NC unconnected No internal connection.
11 SCL2 bidirectional Side-2 I2C serial clock line. Open-drain bidirectional; requires external pull-up to VDD2. Higher drive strength than side 1 (up to 35 mA sink).
12 SDA2 bidirectional Side-2 I2C serial data line. Open-drain bidirectional; requires external pull-up to VDD2. Sink capability up to 35 mA (VOL2 ≤ 0.4 V).
13 NC unconnected No internal connection.
14 VDD2 power_in Isolator side-2 supply voltage. Operating range 3.0 V to 5.5 V; bypass to GND2 with a local decoupling capacitor (typ. 0.1 µF).
15 NC unconnected No internal connection.
16 GND2 power_in Side-2 reference ground (internally tied to pin 9).
