What's included in this listing 5 pieces of the 74HC14D hex inverter with Schmitt trigger inputs, in SOIC14 package (Q100,118 variant). Typical applications and use cases Debouncing mechanical switches: feed a switch output into one of the inverters to produce a clean digital edge for a microcontroller or FPGA. Signal conditioning for noisy or slow signals: transform noisy signals into stable, fast digital transitions suitable for subsequent logic stages. RC timing and oscillator circuits: create simple delay lines or oscillators by cascading inverters with RC networks for timing or pulse shaping. Logic level interfacing and buffering: use as a noninverting buffer configuration by cascading odd numbers of inverters to achieve desired drive and buffering characteristics for digital signals. Usage notes Supply and inputs: operate from the device's typical CMOS voltage range; ensure Vcc and ground are correctly connected and that input voltages remain within the specified limits to avoid damage. Loading considerations: outputs can drive standard CMOS/TTL compatible inputs; avoid excessive loading to maintain fast transitions and desired timing. Circuit design: cascading multiple inverters can create longer propagation delays or specific buffering behavior; use the Schmitt trigger characteristic to improve stability with slow edges.
