SN74LS37N from Texas Instruments, in a PDIP-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; the function table gives output Y low only when both A and B are high. |
| 2 | 1B | input | Gate 1 input B of the 2-input NAND buffer. |
| 3 | 1Y | output | Gate 1 NAND buffer output. |
| 4 | 2A | input | Gate 2 input A of the 2-input NAND buffer. |
| 5 | 2B | input | Gate 2 input B of the 2-input NAND buffer. |
| 6 | 2Y | output | Gate 2 NAND buffer output. |
| 7 | GND | power_in | Ground terminal; the datasheet gives voltage values with respect to the network ground terminal. |
| 8 | 3Y | output | Gate 3 NAND buffer output. |
| 9 | 3A | input | Gate 3 input A of the 2-input NAND buffer. |
| 10 | 3B | input | Gate 3 input B of the 2-input NAND buffer. |
| 11 | 4Y | output | Gate 4 NAND buffer output. |
| 12 | 4A | input | Gate 4 input A of the 2-input NAND buffer. |
| 13 | 4B | input | Gate 4 input B of the 2-input NAND buffer. |
| 14 | VCC | power_in | Supply voltage with an absolute maximum rating of 7 V. |
