What are the key features of CD74AC14EE4?
- 6-channel hex Schmitt-trigger inverter with built-in hysteresis for noise-immune edge conditioning in AC CMOS
- 24 mA output sink current per channel enabling direct drive of LEDs and logic bus loads without external buffers
- RoHS-compliant 14-pin PDIP package with 50 pF load capacitance for through-hole prototyping and production boards
What is CD74AC14EE4 used for?
The CD74AC14EE4 is used in digital systems where slow-rising or noisy input signals must be converted to clean logic transitions, such as crystal oscillator buffers and RC-coupled clock inputs. Its Schmitt-trigger hysteresis prevents multiple output transitions caused by input signal bounce, making it ideal for pushbutton debouncing and sensor output conditioning. The high 24 mA drive strength supports direct LED indicators and bus termination in industrial and embedded control designs.

Frequently Asked Questions
What output drive current does the CD74AC14EE4 provide per channel, and what loads can it directly drive?
Each of the 6 Schmitt-trigger inverter channels in the CD74AC14EE4 can sink up to 24 mA of output current. This drive strength is sufficient to directly drive standard LEDs, TTL logic inputs, and short PCB bus lines without needing external buffer transistors, simplifying the overall design at 50 pF load capacitance.
How does the Schmitt-trigger input hysteresis of the CD74AC14EE4 improve signal integrity in noisy environments?
The Schmitt-trigger inputs of the CD74AC14EE4 incorporate built-in hysteresis, meaning the threshold for switching from low-to-high differs from the high-to-low switching threshold. This voltage gap prevents output chatter when the input signal rises or falls slowly, such as with RC time constant circuits or noisy sensor outputs in industrial environments.
For which design scenarios is the CD74AC14EE4 preferred over a standard 74HC04 hex inverter?
The CD74AC14EE4 is preferred over a standard 74HC04 when the input signal has slow edges, excessive noise, or undefined transition regions, since the Schmitt-trigger hysteresis guarantees a single clean output transition even under these conditions. Additionally, the AC family's 24 mA sink current outperforms the HC family's 4 mA, making it better for driving heavier loads at 50 pF or more.
