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.
