PI3V312QEX from Diodes Incorporated, 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 | S | input | Select input that chooses the source channel: S=L connects IA0-ID0 to YA-YD and S=H connects IA1-ID1 to YA-YD, and it may be driven up to 3.6V regardless of supply voltage. |
| 2 | IA0 | input | Data input A0 (channel 0 of port A), 5V I/O tolerant with 3.3V supply, passed to YA through the 5Ω switch when S=L. |
| 3 | IA1 | input | Data input A1 (channel 1 of port A), 5V I/O tolerant with 3.3V supply, passed to YA through the 5Ω switch when S=H. |
| 4 | YA | tri_state | Data output A of the 2:1 mux/demux with 3-state capability, placed in Hi-Z when EN is H, and connected to IA0 or IA1 through a 5Ω switch. |
| 5 | IB0 | input | Data input B0 (channel 0 of port B), 5V I/O tolerant with 3.3V supply, passed to YB when S=L. |
| 6 | IB1 | input | Data input B1 (channel 1 of port B), 5V I/O tolerant with 3.3V supply, passed to YB when S=H. |
| 7 | YB | tri_state | Data output B of the 2:1 mux/demux with 3-state capability, placed in Hi-Z when EN is H, and connected to IB0 or IB1 through a 5Ω switch. |
| 8 | GND | power_in | Ground reference for the device. |
| 9 | YC | tri_state | Data output C of the 2:1 mux/demux with 3-state capability, placed in Hi-Z when EN is H, and connected to IC0 or IC1 through a 5Ω switch. |
| 10 | IC1 | input | Data input C1 (channel 1 of port C), 5V I/O tolerant with 3.3V supply, passed to YC when S=H. |
| 11 | IC0 | input | Data input C0 (channel 0 of port C), 5V I/O tolerant with 3.3V supply, passed to YC when S=L. |
| 12 | YD | tri_state | Data output D of the 2:1 mux/demux with 3-state capability, placed in Hi-Z when EN is H, and connected to ID0 or ID1 through a 5Ω switch. |
| 13 | ID1 | input | Data input D1 (channel 1 of port D), 5V I/O tolerant with 3.3V supply, passed to YD when S=H. |
| 14 | ID0 | input | Data input D0 (channel 0 of port D), 5V I/O tolerant with 3.3V supply, passed to YD when S=L. |
| 15 | EN | input | Enable input: EN=H disables the switch and puts all Y outputs in Hi-Z, EN=L enables the selected path, and it may be driven up to 3.6V regardless of supply voltage. |
| 16 | VCC | power_in | Power supply for 1.8V, 2.5V or 3.3V operation; the DC characteristics are specified at 3.3V ±10% and 2.5V ±10%, with absolute maximum VCC of -0.5V to +4.6V. |
