Description

The MC74VHC14DTR2G is a high-speed CMOS Schmitt-trigger inverter manufactured by ON Semiconductor. It is part of the VHC (Very High-Speed CMOS) series, designed to operate with low power consumption while providing fast switching times. The device contains six independent inverters with Schmitt-trigger inputs, which provide hysteresis for noise immunity and signal stability, making it ideal for applications with slow or noisy input signals.
Key features include a wide supply voltage range of 2V to 5.5V, compatibility with TTL input levels, and low static power consumption. The Schmitt-trigger action ensures that the output switches cleanly and predictably, even with slowly changing input signals. This makes the MC74VHC14DTR2G suitable for use in various digital applications, such as waveform shaping, signal conditioning, and interfacing standard logic families.
Packaged in a compact SOIC-14 surface-mount format, it is also available in a tape and reel configuration, making it convenient for automated assembly processes.
