ADUM140E1BRQZ 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 | VDD1 | power_in | Supply Voltage for Isolator Side 1; the device operates with the supply on either side ranging from 1.8 V to 5 V. |
| 2 | GND1 | power_in | Ground Reference for Isolator Side 1 (pins 2 and 8 are both GND1). |
| 3 | VIA | input | Logic Input A on isolator side 1. |
| 4 | VIB | input | Logic Input B on isolator side 1. |
| 5 | VIC | input | Logic Input C on isolator side 1. |
| 6 | VID | input | Logic Input D on isolator side 1. |
| 7 | NIC | unconnected | No Internal Connection; leave this pin floating. |
| 8 | GND1 | power_in | Ground Reference for Isolator Side 1 (pins 2 and 8 are both GND1). |
| 9 | GND2 | power_in | Ground Reference for Isolator Side 2 (pins 9 and 15 are both GND2). |
| 10 | VE2 | input | Output Enable 2; active-high logic input where VE2 high or disconnected enables VOA-VOD, and VE2 low disables them to high-Z. |
| 11 | VOD | output | Logic Output D on isolator side 2. |
| 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 Reference for Isolator Side 2 (pins 9 and 15 are both GND2). |
| 16 | VDD2 | power_in | Supply Voltage for Isolator Side 2; the device operates with the supply on either side ranging from 1.8 V to 5 V. |
