**JSMSEMI** · Logic Gates · SOP-14

SN74HC08DR-JSM from JSMSEMI, in a SOP-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 | 1A | input | Data input A of gate 1 (2-input AND). |
| 2 | 1B | input | Data input B of gate 1 (2-input AND). |
| 3 | 1Y | output | Data output of gate 1. |
| 4 | 2A | input | Data input A of gate 2 (2-input AND). |
| 5 | 2B | input | Data input B of gate 2 (2-input AND). |
| 6 | 2Y | output | Data output of gate 2; the pin table labels it 'input/output', but the logic diagram shows it as an output. |
| 7 | GND | power_in | Ground (0V). |
| 8 | 3Y | output | Data output of gate 3. |
| 9 | 3A | input | Data input A of gate 3 (2-input AND). |
| 10 | 3B | input | Data input B of gate 3 (2-input AND). |
| 11 | 4Y | output | Data output of gate 4. |
| 12 | 4A | input | Data input A of gate 4 (2-input AND). |
| 13 | 4B | input | Data input B of gate 4 (2-input AND). |
| 14 | Vcc | power_in | Supply voltage; recommended 2.0V to 6.0V (5.0V typ), absolute maximum -0.5V to +7V. |
