SN74CBTLV3251DR from Texas Instruments, in a SOIC-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 | B4 | bidirectional | Bidirectional data I/O for multiplexer channel 4, connected to A through 5Ω FET switch when selected. |
| 2 | B3 | bidirectional | Bidirectional data I/O for multiplexer channel 3, connected to A through 5Ω FET switch when selected. |
| 3 | B2 | bidirectional | Bidirectional data I/O for multiplexer channel 2, connected to A through 5Ω FET switch when selected. |
| 4 | B1 | bidirectional | Bidirectional data I/O for multiplexer channel 1, connected to A through 5Ω FET switch when selected. |
| 5 | A | bidirectional | Common bidirectional data port connected to one of eight B channels through 5Ω FET switch as determined by S0:S2 address inputs. |
| 6 | NC | unconnected | No internal connection. |
| 7 | OE | input | Output enable control input, active low; places all channels in high-impedance state when high. |
| 8 | GND | power_in | Ground reference. |
| 9 | S2 | input | Multiplexer address select input bit 2. |
| 10 | S1 | input | Multiplexer address select input bit 1. |
| 11 | S0 | input | Multiplexer address select input bit 0. |
| 12 | B8 | bidirectional | Bidirectional data I/O for multiplexer channel 8, connected to A through 5Ω FET switch when selected. |
| 13 | B7 | bidirectional | Bidirectional data I/O for multiplexer channel 7, connected to A through 5Ω FET switch when selected. |
| 14 | B6 | bidirectional | Bidirectional data I/O for multiplexer channel 6, connected to A through 5Ω FET switch when selected. |
| 15 | B5 | bidirectional | Bidirectional data I/O for multiplexer channel 5, connected to A through 5Ω FET switch when selected. |
| 16 | VCC | power_out | Positive power supply, 2.3 V to 3.6 V operating range. |
