**Texas Instruments** · Inverters · SOIC-14

SN74ACT04IDREP 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 | Data input of inverter 1; the input is TTL-voltage compatible and accepts voltages up to 5.5 V. |
| 2 | 1Y | output | Output of inverter 1 (Y = A); at recommended conditions it supplies IOH of −24 mA and sinks IOL of 24 mA. |
| 3 | 2A | input | Data input of inverter 2; the input is TTL-voltage compatible and accepts voltages up to 5.5 V. |
| 4 | 2Y | output | Output of inverter 2 (Y = A); at recommended conditions it supplies IOH of −24 mA and sinks IOL of 24 mA. |
| 5 | 3A | input | Data input of inverter 3; the input is TTL-voltage compatible and accepts voltages up to 5.5 V. |
| 6 | 3Y | output | Output of inverter 3 (Y = A); at recommended conditions it supplies IOH of −24 mA and sinks IOL of 24 mA. |
| 7 | GND | power_in | Ground reference for the device; unused inputs must be held at VCC or GND for proper operation. |
| 8 | 4Y | output | Output of inverter 4 (Y = A); at recommended conditions it supplies IOH of −24 mA and sinks IOL of 24 mA. |
| 9 | 4A | input | Data input of inverter 4; the input is TTL-voltage compatible and accepts voltages up to 5.5 V. |
| 10 | 5Y | output | Output of inverter 5 (Y = A); at recommended conditions it supplies IOH of −24 mA and sinks IOL of 24 mA. |
| 11 | 5A | input | Data input of inverter 5; the input is TTL-voltage compatible and accepts voltages up to 5.5 V. |
| 12 | 6Y | output | Output of inverter 6 (Y = A); at recommended conditions it supplies IOH of −24 mA and sinks IOL of 24 mA. |
| 13 | 6A | input | Data input of inverter 6; the input is TTL-voltage compatible and accepts voltages up to 5.5 V. |
| 14 | VCC | power_in | Supply voltage, 4.5 V to 5.5 V recommended operating range. |
