74HC04BQ from Nexperia, in a DHVQFN-14-EP(2.5x3). 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 clamp diodes allow current-limiting resistors for inputs above VCC, with input clamping current limited to ±20 mA. |
| 2 | 1Y | output | Data output of inverter 1 (Y = NOT A); output current is limited to ±25 mA. |
| 3 | 2A | input | Data input of inverter 2; the input clamp diodes allow current-limiting resistors for inputs above VCC, with input clamping current limited to ±20 mA. |
| 4 | 2Y | output | Data output of inverter 2 (Y = NOT A); output current is limited to ±25 mA. |
| 5 | 3A | input | Data input of inverter 3; the input clamp diodes allow current-limiting resistors for inputs above VCC, with input clamping current limited to ±20 mA. |
| 6 | 3Y | output | Data output of inverter 3 (Y = NOT A); output current is limited to ±25 mA. |
| 7 | GND | power_in | Ground (0 V) reference for all voltages; ground current is rated at -50 mA. |
| 8 | 4Y | output | Data output of inverter 4 (Y = NOT A); output current is limited to ±25 mA. |
| 9 | 4A | input | Data input of inverter 4; the input clamp diodes allow current-limiting resistors for inputs above VCC, with input clamping current limited to ±20 mA. |
| 10 | 5Y | output | Data output of inverter 5 (Y = NOT A); output current is limited to ±25 mA. |
| 11 | 5A | input | Data input of inverter 5; the input clamp diodes allow current-limiting resistors for inputs above VCC, with input clamping current limited to ±20 mA. |
| 12 | 6Y | output | Data output of inverter 6 (Y = NOT A); output current is limited to ±25 mA. |
| 13 | 6A | input | Data input of inverter 6; the input clamp diodes allow current-limiting resistors for inputs above VCC, with input clamping current limited to ±20 mA. |
| 14 | VCC | power_in | Supply voltage: 2.0 V to 6.0 V for 74HC04 and 4.5 V to 5.5 V for 74HCT04; absolute maximum is -0.5 V to +7 V. |
| 15 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
