SN74CBTLV3125DR from Texas Instruments, in a SOIC-14. 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 | 1OE | input | Output enable for channel 1, active high; the switch is disabled when this input is high (VIH min 2 V at VCC 2.7-3.6 V). |
| 2 | 1A | bidirectional | Channel 1 input or output, connected to 1B through the FET switch (5Ω switch connection). |
| 3 | 1B | bidirectional | Channel 1 input or output, connected to 1A through the FET switch (5Ω switch connection). |
| 4 | 2OE | input | Output enable for channel 2, active high; the switch is disabled when this input is high (VIH min 2 V at VCC 2.7-3.6 V). |
| 5 | 2A | bidirectional | Channel 2 input or output, connected to 2B through the FET switch (5Ω switch connection). |
| 6 | 2B | bidirectional | Channel 2 input or output, connected to 2A through the FET switch (5Ω switch connection). |
| 7 | GND | power_in | Ground. |
| 8 | 3B | bidirectional | Channel 3 input or output, connected to 3A through the FET switch (5Ω switch connection). |
| 9 | 3A | bidirectional | Channel 3 input or output, connected to 3B through the FET switch (5Ω switch connection). |
| 10 | 3OE | input | Output enable for channel 3, active high; the switch is disabled when this input is high (VIH min 2 V at VCC 2.7-3.6 V). |
| 11 | 4B | bidirectional | Channel 4 input or output, connected to 4A through the FET switch (5Ω switch connection). |
| 12 | 4A | bidirectional | Channel 4 input or output, connected to 4B through the FET switch (5Ω switch connection). |
| 13 | 4OE | input | Output enable for channel 4, active high; the switch is disabled when this input is high (VIH min 2 V at VCC 2.7-3.6 V). |
| 14 | VCC | power_in | Power supply, recommended 2.3 V to 3.6 V (absolute maximum 4.6 V). |
