SN74HC08N / SN74HC11N / SN74HC14N DIP-14 Logic Gate ICs — AND, 3-Input AND, Schmitt Inverter (5-Pack)
This listing covers three essential SN74HC series DIP-14 logic gate ICs: the SN74HC08N (quad 2-input AND), SN74HC11N (triple 3-input AND), and SN74HC14N (hex Schmitt-trigger inverter). All operate from 2–6V, are compatible with 3.3V and 5V logic, and are rated from -40°C to +125°C. Select your required variant from the dropdown.

Why Choose SN74HC Series?
- 2–6V operation — compatible with both 3.3V (ESP32, STM32) and 5V (Arduino) systems
- ±25mA output — directly drives LEDs and logic inputs without buffers
- DIP-14 breadboard-friendly — plugs directly into standard 2.54mm breadboards
- SN74HC14N Schmitt trigger — hysteresis eliminates noise-induced false triggering on slow or noisy signals
- Texas Instruments quality — industry-standard parts with comprehensive datasheet support
Compatible With / Common Use Cases
- SN74HC08N (AND gate): Enable/disable signal gating, combinational logic, interrupt masking in Arduino/STM32 circuits
- SN74HC11N (3-input AND): 3-condition enable logic, address decoding, complex combinational logic
- SN74HC14N (Schmitt inverter): Button debounce circuit, RC oscillator, slow signal squaring, crystal oscillator buffer, noise-immune signal conditioning
Frequently Asked Questions
Q: How do I use SN74HC14N to debounce a push button for Arduino?
A: Connect the button between VCC and the input pin, with a 10kΩ pull-down resistor to GND. Connect the input to one SN74HC14N inverter input. The Schmitt trigger hysteresis (~0.9V at 5V) prevents multiple transitions during button bounce. The output will be a clean logic signal — invert again with a second gate if needed for active-high output.
Q: Can SN74HC14N be used as a simple RC oscillator?
A: Yes. Connect a resistor (R) from output to input, and a capacitor (C) from input to GND. The Schmitt trigger hysteresis creates a relaxation oscillator with frequency approximately f ≈ 1/(1.2 × R × C). Use R = 10kΩ and C = 10nF for ~8kHz, or adjust R/C for your target frequency.
Q: What is the difference between SN74HC14 and CD40106?
A: Both are hex Schmitt-trigger inverters. SN74HC14 operates from 2–6V with faster switching (~7ns) and higher output current (±25mA). CD40106 operates from 3–18V (wider range) but is slower. Use SN74HC14 for 3.3V/5V digital systems; use CD40106 when you need higher supply voltage compatibility.
