Overview
The M74HC14YTTR is a high-speed CMOS hex Schmitt inverter manufactured by STMicroelectronics. It is fabricated using silicon gate C2MOS technology and features the same pin configuration and functions as the M74HC04, but with the addition of a 20% VCC hysteresis level on all inputs. This hysteresis, combined with the Schmitt trigger function, enhances the device's ability to handle slow rise/fall input signals, making it suitable for use in line receivers.
