MM74HC14MX from onsemi, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A1 | input | Schmitt-trigger input of inverter 1. DC input voltage range 0 to VCC (abs max -1.5V to VCC+1.5V). Typical positive-going threshold 2.7V, negative-going 1.8V at VCC=4.5V. |
| 2 | Y1 | output | Inverted CMOS output of inverter 1 (Y1 = /A1). Guaranteed |
| 3 | A2 | input | Schmitt-trigger input of inverter 2. Same electrical characteristics as A1. |
| 4 | Y2 | output | Inverted CMOS output of inverter 2 (Y2 = /A2). |
| 5 | A3 | input | Schmitt-trigger input of inverter 3. Same electrical characteristics as A1. |
| 6 | Y3 | output | Inverted CMOS output of inverter 3 (Y3 = /A3). |
| 7 | GND | power_in | Ground reference (0V). Abs max ICC current ±50mA per pin. |
| 8 | Y4 | output | Inverted CMOS output of inverter 4 (Y4 = /A4). |
| 9 | A4 | input | Schmitt-trigger input of inverter 4. Same electrical characteristics as A1. |
| 10 | Y5 | output | Inverted CMOS output of inverter 5 (Y5 = /A5). |
| 11 | A5 | input | Schmitt-trigger input of inverter 5. Same electrical characteristics as A1. |
| 12 | Y6 | output | Inverted CMOS output of inverter 6 (Y6 = /A6). |
| 13 | A6 | input | Schmitt-trigger input of inverter 6. Same electrical characteristics as A1. |
| 14 | VCC | power_in | Positive supply rail. Recommended 2V to 6V; abs max -0.5V to +7.0V. Quiescent current 20µA max at 25°C. |
