Texas Instruments · Inverters · TSSOP-14
SN74HC14QPWRG4Q1 from Texas Instruments, in a TSSOP-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 | Channel 1 Schmitt-trigger input A; input voltage must stay within 0 V to VCC, and unused inputs must be tied to VCC or GND rather than left floating. |
| 2 | 1Y | output | Channel 1 output Y (Y = A inverted); output swings between 0 V and VCC, and it can be left floating when unused but must not be connected directly to VCC or ground. |
| 3 | 2A | input | Channel 2 Schmitt-trigger input A; input voltage must stay within 0 V to VCC, and unused inputs must be tied to VCC or GND rather than left floating. |
| 4 | 2Y | output | Channel 2 output Y (Y = A inverted); output swings between 0 V and VCC, and it can be left floating when unused but must not be connected directly to VCC or ground. |
| 5 | 3A | input | Channel 3 Schmitt-trigger input A; input voltage must stay within 0 V to VCC, and unused inputs must be tied to VCC or GND rather than left floating. |
| 6 | 3Y | output | Channel 3 output Y (Y = A inverted); output swings between 0 V and VCC, and it can be left floating when unused but must not be connected directly to VCC or ground. |
| 7 | GND | power_in | Ground reference for the device; the ground voltage is used to produce the output LOW level. |
| 8 | 4Y | output | Channel 4 output Y (Y = A inverted); output swings between 0 V and VCC, and it can be left floating when unused but must not be connected directly to VCC or ground. |
| 9 | 4A | input | Channel 4 Schmitt-trigger input A; input voltage must stay within 0 V to VCC, and unused inputs must be tied to VCC or GND rather than left floating. |
| 10 | 5Y | output | Channel 5 output Y (Y = A inverted); output swings between 0 V and VCC, and it can be left floating when unused but must not be connected directly to VCC or ground. |
| 11 | 5A | input | Channel 5 Schmitt-trigger input A; input voltage must stay within 0 V to VCC, and unused inputs must be tied to VCC or GND rather than left floating. |
| 12 | 6Y | output | Channel 6 output Y (Y = A inverted); output swings between 0 V and VCC, and it can be left floating when unused but must not be connected directly to VCC or ground. |
| 13 | 6A | input | Channel 6 Schmitt-trigger input A; input voltage must stay within 0 V to VCC, and unused inputs must be tied to VCC or GND rather than left floating. |
| 14 | VCC | power_in | Positive supply; recommended operating range is 2 V to 6 V (absolute maximum 7 V), with a 0.1-µF bypass capacitor placed close to the pin. |
