CD74HC4002PWR from Texas Instruments, 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 | Gate 1 output, high only when all four gate 1 inputs (1A-1D) are low. |
| 2 | 1A | input | Gate 1 input A; a high level forces 1Y low. |
| 3 | 1B | input | Gate 1 input B; a high level forces 1Y low. |
| 4 | 1C | input | Gate 1 input C; a high level forces 1Y low. |
| 5 | 1D | input | Gate 1 input D; a high level forces 1Y low. |
| 6 | NC | unconnected | No internal connection. |
| 7 | GND | power_in | Ground reference for the device. |
| 8 | NC | unconnected | No internal connection. |
| 9 | 2A | input | Gate 2 input A; a high level forces 2Y low. |
| 10 | 2B | input | Gate 2 input B; a high level forces 2Y low. |
| 11 | 2C | input | Gate 2 input C; a high level forces 2Y low. |
| 12 | 2D | input | Gate 2 input D; a high level forces 2Y low. |
| 13 | 2Y | output | Gate 2 output, high only when all four gate 2 inputs (2A-2D) are low. |
| 14 | VCC | power_in | Supply voltage, 2 V to 6 V for HC types, with a 0.1-µF bypass capacitor recommended close to the pin. |
