**Texas Instruments** · Inverters · PDIP-14

SN74ALS05AN 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 | Input of inverter 1; the output 1Y follows the logic function Y = A. |
| 2 | 1Y | output | Open-collector output of inverter 1, which requires a pullup resistor to operate correctly. |
| 3 | 2A | input | Input of inverter 2; the output 2Y follows the logic function Y = A. |
| 4 | 2Y | output | Open-collector output of inverter 2, which requires a pullup resistor to operate correctly. |
| 5 | 3A | input | Input of inverter 3; the output 3Y follows the logic function Y = A. |
| 6 | 3Y | output | Open-collector output of inverter 3, which requires a pullup resistor to operate correctly. |
| 7 | GND | power_in | Ground reference for the device. |
| 8 | 4Y | output | Open-collector output of inverter 4, which requires a pullup resistor to operate correctly. |
| 9 | 4A | input | Input of inverter 4; the output 4Y follows the logic function Y = A. |
| 10 | 5Y | output | Open-collector output of inverter 5, which requires a pullup resistor to operate correctly. |
| 11 | 5A | input | Input of inverter 5; the output 5Y follows the logic function Y = A. |
| 12 | 6Y | output | Open-collector output of inverter 6, which requires a pullup resistor to operate correctly. |
| 13 | 6A | input | Input of inverter 6; the output 6Y follows the logic function Y = A. |
| 14 | VCC | power_in | Supply voltage, specified at 4.5 V to 5.5 V with a nominal 5 V. |
