SN74HC14QPWRG4Q1

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.
