SN74LS14DR from Texas Instruments, 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 | 1A | input | Channel 1 Schmitt-trigger inverter input. TTL-compatible input with hysteresis; V_T+ typ 1.6 V, V_T- typ 0.8 V at V_CC = 5 V (SN74LS14). |
| 2 | 1Y | output | Channel 1 inverter output. Totem-pole output; drives I_OL up to 8 mA (V_OL max 0.5 V) and I_OH up to -0.4 mA (V_OH min 2.4 V) for SN74LS14. |
| 3 | 2A | input | Channel 2 Schmitt-trigger inverter input. |
| 4 | 2Y | output | Channel 2 inverter output. |
| 5 | 3A | input | Channel 3 Schmitt-trigger inverter input. |
| 6 | 3Y | output | Channel 3 inverter output. |
| 7 | GND | power_in | Ground reference for the device (0 V). |
| 8 | 4Y | output | Channel 4 inverter output. |
| 9 | 4A | input | Channel 4 Schmitt-trigger inverter input. |
| 10 | 5Y | output | Channel 5 inverter output. |
| 11 | 5A | input | Channel 5 Schmitt-trigger inverter input. |
| 12 | 6Y | output | Channel 6 inverter output. |
| 13 | 6A | input | Channel 6 Schmitt-trigger inverter input. |
| 14 | VCC | power_in | Positive supply. Recommended V_CC = 4.75 V to 5.25 V (nom 5 V) for SN74LS14; absolute maximum 7 V. Decouple with a 0.1 uF ceramic cap to GND close to the pin. |
