Applications
The CD74ACT14M is widely used for signal conditioning and wave-shaping in digital systems where slow or noisy input signals must be converted to clean logic levels. Its Schmitt-trigger hysteresis makes it ideal for debouncing mechanical switches, conditioning oscillator outputs, and interfacing sensors to microcontrollers. It is also used in clock distribution, RC oscillator circuits, and bus line conditioning in industrial and consumer electronics.

Frequently Asked Questions
What makes the CD74ACT14M different from a standard hex inverter?
The CD74ACT14M includes Schmitt-trigger hysteresis on each of its 6 inputs, meaning it tolerates slow signal edges and noisy inputs that would cause multiple transitions in a standard inverter. This results in cleaner, glitch-free output transitions even with degraded input signals.
What is the output current capability of the CD74ACT14M?
The CD74ACT14M has a maximum output low current (IOL) of 24 mA per output, allowing it to directly drive LEDs, logic gates, and moderate capacitive loads, which is significantly higher than standard HC family parts rated at 8 mA.
What package does the CD74ACT14M use?
The CD74ACT14M is housed in a 14-pin SOIC package (JESD-30 code R-PDSO-G14, MS-012AB outline), offering a small surface-mount footprint suitable for high-density PCBs while providing easy soldering and inspection.
What logic family is the CD74ACT14M and what supply voltage does it support?
The CD74ACT14M is part of the ACT (Advanced CMOS TTL-compatible) logic family, designed to operate at 5V supply voltage with TTL-compatible input thresholds, making it directly interchangeable with 74ACT14 devices from other manufacturers.
What are common applications for the CD74ACT14M?
Common applications include mechanical switch debouncing, RC oscillator construction, signal wave-shaping, clock buffering, and noise-immune logic level conversion. The Schmitt-trigger inputs make it especially useful wherever signal integrity is compromised by long PCB traces or inductive coupling.
