The NXP HEF4016B is a monolithic integrated circuit that provides six independent inverting Schmitt-trigger gates within a compact 14-pin DIP or SO package. As part of the widely used HEF4000 family, it leverages standard CMOS technology, making it a versatile and robust solution for a variety of digital and waveform shaping applications.

A key advantage of this IC is its wide supply voltage range from 3V to 15V, allowing it to be used across multiple logic level standards and in both battery-operated and line-powered systems. This flexibility is complemented by very high input impedance and low power consumption, which are characteristic benefits of CMOS-based designs. These features make the HEF4016B suitable for power-sensitive applications and help minimize loading effects on signal sources.

The most significant feature of the HEF4016B is the built-in hysteresis in each of its six gates. This hysteresis creates two distinct voltage thresholds—one for rising input signals and another for falling ones—enabling the device to effectively reject noise on slow-moving or noisy input signals. As a result, it excels at converting irregular or sinusoidal waveforms into clean, sharp digital outputs, and is commonly used in switch debouncing circuits, pulse shaping, and oscillator designs.
