SN74HC02PW from lingxingic, in a TSSOP-14. 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 | 1Y | output | Data output of NOR gate 1; per the function table, 1Y is H only when both 1A and 1B are L. |
| 2 | 1A | input | Data input A of NOR gate 1, which is part of the 2-input NOR function Y = NOT(A OR B). |
| 3 | 1B | input | Data input B of NOR gate 1, which is part of the 2-input NOR function Y = NOT(A OR B). |
| 4 | 2Y | output | Data output of NOR gate 2; per the function table, 2Y is H only when both 2A and 2B are L. |
| 5 | 2A | input | Data input A of NOR gate 2, which is part of the 2-input NOR function Y = NOT(A OR B). |
| 6 | 2B | input | Data input B of NOR gate 2, which is part of the 2-input NOR function Y = NOT(A OR B). |
| 7 | GND | power_in | Ground reference (0 V); the datasheet states GND = 0 V for all tested conditions. |
| 8 | 3A | input | Data input A of NOR gate 3, which is part of the 2-input NOR function Y = NOT(A OR B). |
| 9 | 3B | input | Data input B of NOR gate 3, which is part of the 2-input NOR function Y = NOT(A OR B). |
| 10 | 3Y | output | Data output of NOR gate 3; per the function table, 3Y is H only when both 3A and 3B are L. |
| 11 | 4A | input | Data input A of NOR gate 4, which is part of the 2-input NOR function Y = NOT(A OR B). |
| 12 | 4B | input | Data input B of NOR gate 4, which is part of the 2-input NOR function Y = NOT(A OR B). |
| 13 | 4Y | output | Data output of NOR gate 4; per the function table, 4Y is H only when both 4A and 4B are L. |
| 14 | VCC | power_in | Supply voltage; the recommended range is 2.0 V to 6.0 V for SN74HC02 and 4.5 V to 5.5 V for SN74HCT02. |
