Additional Details

The TC7SH14FU(5RSN,JFT inverts the input signal. The Schmitt trigger inputs have different threshold voltages for rising and falling signals, creating hysteresis. This hysteresis prevents the output from oscillating due to small voltage variations at the input. The device uses CMOS technology, ensuring low static power consumption and high noise margins. The package is usually a 5-pin USON package.
