Présentation
Description
The device operates with a supply voltage range typically between 2V and 6V, making it compatible with various systems. It has TTL-compatible inputs and outputs, ensuring it can interface with other logic families easily. The SN74HC14D package is often in a SOIC (Small Outline Integrated Circuit) format, which is suitable for surface-mount technology.
Typical applications include use in circuits that require signal debouncing, pulse shaping, and logic level conversion. The Schmitt-trigger action provides hysteresis, which helps in preventing false triggering due to noise or slow input transitions.

These features make the SN74HC14D suitable for applications requiring signal conditioning, waveform generation, or simple logic inverters.
Pinout
Here is a brief outline of its pin configuration:
1. VCC (Pin 14): Power Supply Voltage.
2. GND (Pin 7): Ground.
3. Inputs/Outputs: The six inverters are organized as follows:
- 1A (Pin 1), 1Y (Pin 2)
- 2A (Pin 3), 2Y (Pin 4)
- 3A (Pin 5), 3Y (Pin 6)
- 4A (Pin 9), 4Y (Pin 8)
- 5A (Pin 11), 5Y (Pin 10)
- 6A (Pin 13), 6Y (Pin 12)
Each input (A) has a corresponding output (Y), where the output is the logical inversion of the input with the added benefit of Schmitt-trigger characteristics, ideal for enhancing signal stability in digital circuits.
