Overview
The 74VHC14MTR is an advanced high-speed CMOS hex Schmitt inverter manufactured by STMicroelectronics. It is fabricated using sub-micron silicon gate and double-layer metal wiring C2MOS technology. This device is designed to provide high noise immunity and stable output, making it suitable for various applications requiring high-speed and low power consumption. The 74VHC14MTR has a pin configuration and function similar to the 74VHC04 but includes hysteresis, which allows it to transform slowly changing input signals into sharply defined, jitter-free output signals.
