Adafruit 74AHCT14 Logic Level Inverter Level Shifter engineering development tool

SKU CH-QTJE-RF6JC

Six inverter channels shift logic levels at 5V on a breadboard-friendly 19.5mm by 9.0mm board

  • TypePrototyping Products
  • Operates at 5V for standard logic levels
  • Inverts signals across six independent channels
  • Breadboard and perf-board friendly 0.8" x 0.4" footprint
  • Lightweight 0.9g design suits portable prototypes
  • Powered by connecting GND and VCC to desired output logic level

Logic Level Inverter for Prototyping

The Adafruit 74AHCT14 provides six inverting channels that translate mismatched logic levels in development circuits. It suits engineers and hobbyists who need to flip signal polarity while shifting between voltage domains during breadboard or perf-board experimentation.

Thermals Noise and Power Draw

The device operates from a single supply connected to GND and VCC at the desired output logic level. Typical use at 5V draws minimal current and produces no audible noise, while the small 19.5mm by 9.0mm by 7.5mm package dissipates negligible heat in normal prototyping workloads.

Six Inverting Channels per Package

Each 74AHCT14 contains six independent inverter pairs that accept high-level inputs as low as 2V and deliver inverted outputs at the VCC rail. This channel count determines whether one package covers the signal count in a given design or whether multiple units are required.

Perguntas sobre este artigo

How do I install the 74AHCT14 on a breadboard and which pins need power?

Place the DIP package across the breadboard centre gap, then connect GND and VCC to your desired output logic level; the chip runs at 5 V and accepts inputs as low as 2 V.

What maintenance or replacement will the 74AHCT14 need over time?

No scheduled maintenance is required; if the chip is damaged by over-voltage or static discharge it must be replaced as a single unit.

What is the first limit that appears under sustained operation?

The absolute maximum supply voltage is 5 V; exceeding this level will cause permanent failure before any thermal limit is reached.
