π140E31S from 2Pai Semi, in a SSOP-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 at 3 V to 5.5 V in the recommended operating conditions. |
| 2 | GND1 | power_in | Ground 1, the ground reference for isolator side 1. |
| 3 | VIA | input | Logic input A on side 1; a low input drives VOA low, and an open input gives the default output state set by the fail-safe option. |
| 4 | VIB | input | Logic input B on side 1; a low input drives VOB low, and an open input gives the default output state set by the fail-safe option. |
| 5 | VIC | input | Logic input C on side 1; a low input drives VOC low, and an open input gives the default output state set by the fail-safe option. |
| 6 | VID | input | Logic input D on side 1; a low input drives VOD low, and an open input gives the default output state set by the fail-safe option. |
| 7 | NC | unconnected | No connect. |
| 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 | NC | unconnected | No connect for π140E3X; this pin is EN2 (output enable, outputs enabled when high or open) only on the π140E6X variant. |
| 11 | VOD | output | Logic output D on side 2, following input VID after the isolation barrier. |
| 12 | VOC | output | Logic output C on side 2, following input VIC after the isolation barrier. |
| 13 | VOB | output | Logic output B on side 2, following input VIB after the isolation barrier. |
| 14 | VOA | output | Logic output A on side 2, following input VIA after the isolation barrier. |
| 15 | GND2 | power_in | Ground 2, the ground reference for isolator side 2. |
| 16 | VDD2 | power_in | Supply voltage for isolator side 2, specified at 3 V to 5.5 V in the recommended operating conditions. |
