74HC14D/C4118 CMOS hex inverting Schmitt trigger IC
The 74HC14D/C4118 from NXP Semiconductors is a high-speed CMOS hex inverting Schmitt trigger IC designed for signal conditioning and waveform shaping applications requiring precise threshold control and noise immunity. This advanced logic device features six independent inverting Schmitt-trigger circuits housed in a compact 14-pin SOIC package, operating from a wide voltage range of 2.0V to 6.0V with typical propagation delay of just 15 ns at 5V supply voltage. The Schmitt-trigger action with hysteresis on each gate ensures clean signal transitions by providing different positive-going (VT+) and negative-going (VT-) threshold voltages, making it ideal for noise filtering, pulse shaping, and oscillator circuits in industrial control systems, consumer electronics, and automotive applications where signal integrity is critical. The 74HC14D/C4118's combination of high noise immunity, balanced propagation delays, and low power consumption (typical ICC of 1 μA) makes it particularly suitable for interfacing with analog sensors, debouncing mechanical switches, and generating stable clock signals in digitally controlled systems.
