Additional Details

The TC7SH126FU(TE85L inverts the input signal, meaning a high input results in a low output, and vice versa. The Schmitt trigger action is characterized by two different threshold voltages for rising and falling input signals, creating a hysteresis effect. This hysteresis prevents the output from rapidly switching due to small voltage fluctuations on the input. The device utilizes CMOS technology, ensuring low static power consumption and high noise margin. Typical package is 5-pin USON.
