74HC151D from Nexperia, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 I3 input Data input I3; one of eight binary inputs to the multiplexer.
2 I2 input Data input I2; one of eight binary inputs to the multiplexer.
3 I1 input Data input I1; one of eight binary inputs to the multiplexer.
4 I0 input Data input I0; one of eight binary inputs to the multiplexer.
5 Y output Multiplexer output; selected input is routed to this output; forced LOW when E is HIGH.
6 Y̅ output Complementary multiplexer output; complement of Y output; forced HIGH when E is HIGH.
7 E input Enable input (active LOW); when HIGH forces Y LOW and Y̅ HIGH regardless of data inputs.
8 GND power_in Ground; 0 V reference.
9 S2 input Common data select input S2 (most significant bit); selects which of the eight inputs routes to output Y.
10 S1 input Common data select input S1 (middle bit); selects which of the eight inputs routes to output Y.
11 S0 input Common data select input S0 (least significant bit); selects which of the eight inputs routes to output Y.
12 I7 input Data input I7; one of eight binary inputs to the multiplexer.
13 I6 input Data input I6; one of eight binary inputs to the multiplexer.
14 I5 input Data input I5; one of eight binary inputs to the multiplexer.
15 I4 input Data input I4; one of eight binary inputs to the multiplexer.
16 VCC power_in Supply voltage; operating range 2.0 V to 6.0 V per recommended operating conditions.
