SN74LS08D from Texas Instruments, in a SOIC-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 | Gate 1 input A; input voltage up to 7 V for the 'LS08. |
| 2 | 1B | input | Gate 1 input B; input voltage up to 7 V for the 'LS08. |
| 3 | 1Y | output | Gate 1 output, Y = A·B (high only when both inputs are high). |
| 4 | 2A | input | Gate 2 input A; input voltage up to 7 V for the 'LS08. |
| 5 | 2B | input | Gate 2 input B; input voltage up to 7 V for the 'LS08. |
| 6 | 2Y | output | Gate 2 output, Y = A·B (high only when both inputs are high). |
| 7 | GND | power_in | Ground; voltage values are specified with respect to this network ground terminal. |
| 8 | 3Y | output | Gate 3 output, Y = A·B (high only when both inputs are high). |
| 9 | 3A | input | Gate 3 input A; input voltage up to 7 V for the 'LS08. |
| 10 | 3B | input | Gate 3 input B; input voltage up to 7 V for the 'LS08. |
| 11 | 4Y | output | Gate 4 output, Y = A·B (high only when both inputs are high). |
| 12 | 4A | input | Gate 4 input A; input voltage up to 7 V for the 'LS08. |
| 13 | 4B | input | Gate 4 input B; input voltage up to 7 V for the 'LS08. |
| 14 | VCC | power_in | Supply voltage, absolute maximum 7 V with respect to GND. |
