74CBTLV3257DS from Nexperia, in a SSOP-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 nB1 when LOW and nB2 when HIGH (when OE is LOW); it has Schmitt-trigger action and tolerates slow input rise and fall times. |
| 2 | 1B1 | bidirectional | B1 input/output of switch 1, connected to 1A when OE is LOW and S is LOW; switch is high-impedance when OE is HIGH. |
| 3 | 1B2 | bidirectional | B2 input/output of switch 1, connected to 1A when OE is LOW and S is HIGH; switch is high-impedance when OE is HIGH. |
| 4 | 1A | bidirectional | A input/output of switch 1, connected to 1B1 or 1B2 as selected by S when OE is LOW; disconnected when OE is HIGH. |
| 5 | 2B1 | bidirectional | B1 input/output of switch 2, connected to 2A when OE is LOW and S is LOW; switch is high-impedance when OE is HIGH. |
| 6 | 2B2 | bidirectional | B2 input/output of switch 2, connected to 2A when OE is LOW and S is HIGH; switch is high-impedance when OE is HIGH. |
| 7 | 2A | bidirectional | A input/output of switch 2, connected to 2B1 or 2B2 as selected by S when OE is LOW; disconnected when OE is HIGH. |
| 8 | GND | power_in | Ground (0 V); all voltages in the datasheet are referenced to GND. |
| 9 | 3A | bidirectional | A input/output of switch 3, connected to 3B1 or 3B2 as selected by S when OE is LOW; disconnected when OE is HIGH. |
| 10 | 3B2 | bidirectional | B2 input/output of switch 3, connected to 3A when OE is LOW and S is HIGH; switch is high-impedance when OE is HIGH. |
| 11 | 3B1 | bidirectional | B1 input/output of switch 3, connected to 3A when OE is LOW and S is LOW; switch is high-impedance when OE is HIGH. |
| 12 | 4A | bidirectional | A input/output of switch 4, connected to 4B1 or 4B2 as selected by S when OE is LOW; disconnected when OE is HIGH. |
| 13 | 4B2 | bidirectional | B2 input/output of switch 4, connected to 4A when OE is LOW and S is HIGH; switch is high-impedance when OE is HIGH. |
| 14 | 4B1 | bidirectional | B1 input/output of switch 4, connected to 4A when OE is LOW and S is LOW; switch is high-impedance when OE is HIGH. |
| 15 | OE | input | Active-LOW output enable input; when HIGH all switches are high-impedance OFF regardless of S, and it should be tied to VCC through a pull-up resistor to ensure the OFF-state during power-up or power-down. |
| 16 | VCC | power_in | Supply voltage, recommended operating range 2.3 V to 3.6 V. |
