Product Overview
National Semiconductor CD4069CN is a CMOS hex inverter integrated circuit containing six independent inverting gates in a 14-pin dual in-line package. Dual-marked MM74C04N, this device operates across a 3V to 15V supply range for general-purpose digital logic, pulse shaping, and oscillator circuits.
Key Features
- Six independent inverting circuits (hex inverter)
- Dual-marked for CD4069CN and MM74C04N compatibility
- Wide supply voltage operating range of 3V to 15V
- Standard 14-pin dual in-line through-hole package (PDIP-14)
- Symmetrical output characteristics for balanced high and low drive
Applications
- Replacing damaged logic ICs in legacy industrial controls and test equipment
- Generating clock pulses and square waves in DIY synthesizer and audio circuits
- Buffering and inverting low-speed digital signals on microcontroller breakout boards
Frequently Asked Questions
Is the CD4069CN pin-compatible with standard 7404 TTL inverters?
While the CD4069CN shares the same 14-pin DIP pinout arrangement as the standard 7404 hex inverter, it is a CMOS device designed for supply voltages from 3V to 15V with high input impedance and lower drive current than standard TTL logic.
How many inverters are integrated into each CD4069CN chip?
Each IC contains six independent inverters, so a circuit requiring twelve inverting lines uses two chips.
Before complex microcontrollers handled every microsecond task, unbuffered CMOS inverters did the unglamorous work of flipping bits and shaping clean clocks. Pop this into your circuit and let honest silicon do the switching.
