TOSHIBA · Signal Switches, Multiplexers, Decoders · SOP-16

TC74HC151AF from TOSHIBA, in a SOP-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 D3 input Data input 3, selected when address C B A = L H H.
2 D2 input Data input 2, selected when address C B A = L H L.
3 D1 input Data input 1, selected when address C B A = L L H.
4 D0 input Data input 0, selected when address C B A = L L L.
5 Y output Non-inverting output that follows the selected data input when strobe is low and is forced low when strobe is high.
6 W output Inverting output that carries the complement of the selected data when strobe is low and is forced high when strobe is high.
7 ST input Active-low strobe input; low transfers the selected data to the outputs, high sets Y low and W high regardless of data or select inputs.
8 GND power_in Ground (0 V) supply pin.
9 C input Address select input C, the most significant of the three-bit address (A, B, C); unused inputs must be tied to VCC or GND.
10 B input Address select input B of the three-bit address (A, B, C); unused inputs must be tied to VCC or GND.
11 A input Address select input A, the least significant of the three-bit address (A, B, C); unused inputs must be tied to VCC or GND.
12 D7 input Data input 7, selected when address C B A = H H H.
13 D6 input Data input 6, selected when address C B A = H H L.
14 D5 input Data input 5, selected when address C B A = H L H.
15 D4 input Data input 4, selected when address C B A = H L L.
16 VCC power_in Positive supply voltage, operating range 2 to 6 V (absolute maximum -0.5 to 7 V).
