Overview
The MC74LVX14DTR2G is an advanced high-speed CMOS Schmitt inverter produced by onsemi. This device is designed to interface 5V systems with 3V systems, thanks to its 5V-tolerant inputs that can handle voltages up to 6.5V. It is pin and functionally compatible with the MC74LVX04 but includes the additional feature of Schmitt trigger inputs, which provide hysteresis and enhanced noise immunity. This makes it ideal for receiving slow input signals and squaring up inputs with slow rise and fall times.
