Product Overview
The Texas Instruments SN74HC14N contains six independent inverters with Schmitt-trigger inputs. It operates across a 2.0V to 6.0V supply range and performs the Boolean function Y = A in positive logic. The Schmitt-trigger architecture provides distinct switching thresholds for positive-going and negative-going signals, delivering high noise immunity and transforming slow or noisy analog waveforms into sharp digital transitions.
Key Features
- 6 independent Schmitt-trigger inverter channels
- Wide operating voltage range: 2.0 V to 6.0 V
- High noise immunity with built-in input hysteresis
- Standard 14-pin plastic DIP (PDIP) through-hole package
- Low quiescent supply current
Applications
- Debouncing mechanical switches and pushbuttons on custom microcontroller interfaces
- Squaring up slow or distorted sensor signals and clock waveforms
- Building simple relaxation oscillators and pulse-generation circuits for maker bench setups
- Replacing damaged logic in legacy industrial controllers and circuit boards
Frequently Asked Questions
What package type is this IC?
This is a standard 14-pin plastic dual in-line package (DIP-14) with 0.300-inch row spacing, designed for through-hole PCB soldering or solderless breadboard prototyping.
What advantage does a Schmitt-trigger input provide?
Schmitt-trigger inputs utilize hysteresis, meaning the switching threshold differs for rising and falling edges. This prevents output jitter and chatter when processing slowly changing or noisy analog inputs.
Why buy an individual component rather than a bulk lot?
Getting a single verified part lets you complete a specific repair or breadboard prototype without paying for unused surplus lot volume. Shipping is $8 flat rate, free once the order passes $28, and orders leave our Idaho warehouse the same or next business day.
Nothing cleans up a noisy signal quite like a reliable Schmitt trigger. Drop it in your circuit and turn messy inputs into crisp, honest square waves.
