Working Principles

The 74AUP1G97FW4-7 is based on the Schmitt-trigger principle, which provides hysteresis in the input voltage levels. This hysteresis ensures that the output transitions occur at different voltage thresholds for rising and falling input signals, improving noise immunity and signal integrity.

When the input voltage exceeds the upper threshold, the output switches to a low state (0V). Conversely, when the input voltage falls below the lower threshold, the output switches to a high impedance state, allowing an external pull-up resistor to pull the output voltage up to VCC.
