SN74LS11DR 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 (AND input; output 1Y is high only when 1A, 1B and 1C are all high). |
| 2 | 1B | input | Gate 1 input B. |
| 3 | 2A | input | Gate 2 input A (AND input; output 2Y is high only when 2A, 2B and 2C are all high). |
| 4 | 2B | input | Gate 2 input B. |
| 5 | 2C | input | Gate 2 input C. |
| 6 | 2Y | output | Gate 2 output, Y = 2A·2B·2C. |
| 7 | GND | power_in | Ground; supply voltage values are specified with respect to this network ground terminal. |
| 8 | 3Y | output | Gate 3 output, Y = 3A·3B·3C. |
| 9 | 3A | input | Gate 3 input A (AND input; output 3Y is high only when 3A, 3B and 3C are all high). |
| 10 | 3B | input | Gate 3 input B. |
| 11 | 3C | input | Gate 3 input C. |
| 12 | 1Y | output | Gate 1 output, Y = 1A·1B·1C. |
| 13 | 1C | input | Gate 1 input C. |
| 14 | VCC | power_in | Positive supply; absolute maximum 7 V with respect to ground. |
