74HCT151D from Nexperia, in a SO-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 I3 input Multiplexer data input I3; inputs include clamp diodes that allow current-limiting resistors for interfacing to voltages above VCC.
2 I2 input Multiplexer data input I2; inputs include clamp diodes that allow current-limiting resistors for interfacing to voltages above VCC.
3 I1 input Multiplexer data input I1; inputs include clamp diodes that allow current-limiting resistors for interfacing to voltages above VCC.
4 I0 input Multiplexer data input I0; inputs include clamp diodes that allow current-limiting resistors for interfacing to voltages above VCC.
5 Y output Multiplexer output, showing the selected data input; it is forced LOW when E is HIGH.
6 ~{Y} output Complementary multiplexer output; it is forced HIGH when E is HIGH.
7 E input Enable input, active LOW; a HIGH on E forces Y LOW and Y HIGH.
8 GND power_in Ground (0 V).
9 S2 input Common data select input (most significant select bit) that chooses which data input is routed to the outputs.
10 S1 input Common data select input that chooses which data input is routed to the outputs.
11 S0 input Common data select input (least significant select bit) that chooses which data input is routed to the outputs.
12 I7 input Multiplexer data input I7; inputs include clamp diodes that allow current-limiting resistors for interfacing to voltages above VCC.
13 I6 input Multiplexer data input I6; inputs include clamp diodes that allow current-limiting resistors for interfacing to voltages above VCC.
14 I5 input Multiplexer data input I5; inputs include clamp diodes that allow current-limiting resistors for interfacing to voltages above VCC.
15 I4 input Multiplexer data input I4; inputs include clamp diodes that allow current-limiting resistors for interfacing to voltages above VCC.
16 VCC power_in Supply voltage: 2.0 V to 6.0 V for 74HC151 and 4.5 V to 5.5 V for 74HCT151 (recommended); absolute maximum -0.5 V to +7 V.
