Pinout
The SN74AC14PWR is a hex Schmitt-trigger inverter IC from Texas Instruments. It has a total of 14 pins. Each of the six inverters within the IC has an input and an output pin, accounting for 12 of the 14 pins. The remaining two pins are for power supply connections: VCC (power supply) and GND (ground).
The Schmitt-trigger functionality of the inverters ensures that they have hysteresis, meaning they are less sensitive to noise on the input signals and can produce cleaner transitions on the output. This makes the SN74AC14PWR ideal for applications that require signal conditioning or noise immunity.
In summary, the key features of the SN74AC14PWR are:
- 14-pin package
- Hex Schmitt-trigger inverters
- Hysteresis for improved noise immunity
- Suitable for applications requiring signal conditioning.
