SN74CBTLV3861DBQR from Texas Instruments, in a QSOP-24. 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 | NC | unconnected | No internal connection. |
| 2 | A1 | bidirectional | Port A bit 1, connected to B1 through the switch when OE is low. |
| 3 | A2 | bidirectional | Port A bit 2, connected to B2 through the switch when OE is low. |
| 4 | A3 | bidirectional | Port A bit 3, connected to B3 through the switch when OE is low. |
| 5 | A4 | bidirectional | Port A bit 4, connected to B4 through the switch when OE is low. |
| 6 | A5 | bidirectional | Port A bit 5, connected to B5 through the switch when OE is low. |
| 7 | A6 | bidirectional | Port A bit 6, connected to B6 through the switch when OE is low. |
| 8 | A7 | bidirectional | Port A bit 7, connected to B7 through the switch when OE is low. |
| 9 | A8 | bidirectional | Port A bit 8, connected to B8 through the switch when OE is low. |
| 10 | A9 | bidirectional | Port A bit 9, connected to B9 through the switch when OE is low. |
| 11 | A10 | bidirectional | Port A bit 10, connected to B10 through the switch when OE is low. |
| 12 | GND | power_in | Ground. |
| 13 | B10 | bidirectional | Port B bit 10, connected to A10 through the switch when OE is low. |
| 14 | B9 | bidirectional | Port B bit 9, connected to A9 through the switch when OE is low. |
| 15 | B8 | bidirectional | Port B bit 8, connected to A8 through the switch when OE is low. |
| 16 | B7 | bidirectional | Port B bit 7, connected to A7 through the switch when OE is low. |
| 17 | B6 | bidirectional | Port B bit 6, connected to A6 through the switch when OE is low. |
| 18 | B5 | bidirectional | Port B bit 5, connected to A5 through the switch when OE is low. |
| 19 | B4 | bidirectional | Port B bit 4, connected to A4 through the switch when OE is low. |
| 20 | B3 | bidirectional | Port B bit 3, connected to A3 through the switch when OE is low. |
| 21 | B2 | bidirectional | Port B bit 2, connected to A2 through the switch when OE is low. |
| 22 | B1 | bidirectional | Port B bit 1, connected to A1 through the switch when OE is low. |
| 23 | OE | input | Output enable: low turns the 10-bit switch on (A = B), high opens it (high impedance); tie to VCC through a pullup resistor to ensure high impedance during power up or power down, and hold at VCC or GND, never floating. |
| 24 | VCC | power_in | Supply voltage, 2.3 V to 3.6 V recommended (absolute maximum -0.5 V to 4.6 V). |
