What are the key features of CD74ACT14MG4?
- 6 independent Schmitt-trigger inverter channels in a single 14-pin SOIC package for space-efficient logic design
- Hysteresis-based Schmitt-trigger inputs reject noise and clean up slow or noisy digital signals reliably
- ACT family compatibility with both TTL and CMOS logic levels, accepting inputs from 2 V to 5.5 V
- 24 mA output sink current enables direct driving of LEDs, optocouplers, and bus loads at 5 V
- 50 pF load capacitance spec ensures clean switching on distributed PCB traces and capacitive loads
What is CD74ACT14MG4 used for?
CD74ACT14MG4 is commonly used to condition noisy or slowly rising digital signals in microcontroller and FPGA interface circuits, converting marginal logic transitions into crisp 5 V ACT-level outputs using built-in Schmitt-trigger hysteresis. The 6 independent inverter channels make it ideal for oscillator circuits, crystal drive networks, and clock signal buffering in industrial control boards and communication equipment. It is also used in signal-level translation and line-receive applications where TTL-compatible inputs must drive CMOS logic at 5 V with guaranteed noise immunity across a -40°C to 85°C industrial temperature range.

Frequently Asked Questions
How does the Schmitt-trigger hysteresis in CD74ACT14MG4 improve signal integrity on slow-edging clock inputs?
CD74ACT14MG4 uses Schmitt-trigger inputs with typical hysteresis of 0.7 V, meaning the output switches high when the input falls below approximately 1.1 V and switches low when the input rises above 1.8 V. This 0.7 V window prevents multiple output transitions caused by noise on slowly rising or falling clock edges, which is common on RC-filtered or long PCB trace signals. As a result, downstream logic receives clean, glitch-free edges even when the source has rise times exceeding 100 ns.
Can CD74ACT14MG4 drive an LED directly, and what limits the output current at 5 V?
Yes, CD74ACT14MG4 can sink up to 24 mA per output pin at 5 V, which is sufficient to drive a standard 20 mA LED when a series resistor of at least 150 Ω is used to set the current. However, total package dissipation limits simultaneous high-current operation on all 6 channels, so practical LED drive is typically limited to 2 or 3 channels at full current. The remaining channels can still perform logic functions without affecting the LED channels if total package current stays within the rated bounds.
What logic family voltage levels does CD74ACT14MG4 accept, and is it compatible with 3.3 V CMOS outputs from a microcontroller?
CD74ACT14MG4 is part of the ACT family, which accepts TTL-compatible input thresholds: a logic high is guaranteed from 2 V and a logic low is guaranteed below 0.8 V. This means 3.3 V CMOS outputs from a microcontroller driving the input high at 3.3 V are fully recognized as a valid logic-1. The supply voltage is 4.5 V to 5.5 V, so the device translates 3.3 V input signals to 5 V ACT output levels, effectively acting as a 3.3 V to 5 V level shifter with inverting Schmitt-trigger conditioning in a single 14-pin package.
For an oscillator circuit using CD74ACT14MG4, what is the typical usable frequency range with a 50 pF capacitor?
CD74ACT14MG4 inverters are commonly used in RC or crystal oscillator circuits where the Schmitt-trigger input provides the hysteresis needed for stable oscillation. With a 50 pF timing capacitor and appropriate resistor values, reliable oscillation is achievable from a few kilohertz up to approximately 20 MHz to 30 MHz using the ACT family's propagation delay of about 7 ns typical. Above 30 MHz, propagation delay and output edge degradation make the inverter unsuitable as a feedback element without careful layout on PCB traces shorter than 20 mm.
