CD74ACT05E 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, TTL-voltage compatible; unused inputs must be held at VCC or GND to ensure proper operation. |
| 2 | 1Y | output | Open-drain output of inverter 1 that requires a pullup resistor to perform correctly. |
| 3 | 2A | input | Input of inverter 2, TTL-voltage compatible; unused inputs must be held at VCC or GND to ensure proper operation. |
| 4 | 2Y | output | Open-drain output of inverter 2 that requires a pullup resistor to perform correctly. |
| 5 | 3A | input | Input of inverter 3, TTL-voltage compatible; unused inputs must be held at VCC or GND to ensure proper operation. |
| 6 | 3Y | output | Open-drain output of inverter 3 that requires a pullup resistor to perform correctly. |
| 7 | GND | power_in | Ground reference for the device. |
| 8 | 4Y | output | Open-drain output of inverter 4 that requires a pullup resistor to perform correctly. |
| 9 | 4A | input | Input of inverter 4, TTL-voltage compatible; unused inputs must be held at VCC or GND to ensure proper operation. |
| 10 | 5Y | output | Open-drain output of inverter 5 that requires a pullup resistor to perform correctly. |
| 11 | 5A | input | Input of inverter 5, TTL-voltage compatible; unused inputs must be held at VCC or GND to ensure proper operation. |
| 12 | 6Y | output | Open-drain output of inverter 6 that requires a pullup resistor to perform correctly. |
| 13 | 6A | input | Input of inverter 6, TTL-voltage compatible; unused inputs must be held at VCC or GND to ensure proper operation. |
| 14 | VCC | power_in | Positive supply; recommended operating range 4.5 V to 5.5 V with an absolute maximum of 6 V. |
