What are the key features of CD54AC04F3A?
- Six independent CMOS inverter gates in AC-series logic, supporting 2 V to 6 V supply operation with propagation delays under 10 ns at 5 V for high-speed signal inversion
- 24 mA output sink current (I_OL) and 50 pF load drive capability enable the CD54AC04F3A to drive bus lines and capacitive loads without external buffers
- 14-pin hermetic ceramic DIP (R-GDIP-T14) package satisfies military and space-grade reliability requirements, providing moisture-proof, long-life packaging for harsh environment deployments
What is CD54AC04F3A used for?
CD54AC04F3A serves signal conditioning, clock buffering, and logic-level inversion functions in military avionics, space electronics, and high-reliability industrial control systems where ceramic packaging is mandated. The six-element AC CMOS inverter array is used to convert active-high enable signals to active-low, drive LED status indicators through 24 mA outputs, and buffer oscillator outputs across 50 pF PCB trace capacitance. Its broad 2 V to 6 V supply compatibility also suits mixed-voltage systems where 3.3 V logic must interface with 5 V TTL-compatible peripherals.

Frequently Asked Questions
What supply voltage range and output drive capability does CD54AC04F3A support?
CD54AC04F3A operates from 2 V to 6 V supply voltage and provides up to 24 mA output sink current (I_OL) per gate with a 50 pF rated load capacitance. This combination allows each of the 6 inverter gates to directly drive LEDs, bus lines, or capacitive PCB traces in 3.3 V and 5 V logic systems without additional buffer stages.
Why is the ceramic DIP package of CD54AC04F3A preferred in military and space applications over plastic alternatives?
The 14-pin hermetic ceramic DIP (R-GDIP-T14) of CD54AC04F3A seals the die against moisture ingress, outgassing, and particulate contamination, which are failure modes that disqualify plastic-packaged logic ICs for MIL-spec and space applications. Ceramic DIPs withstand operating temperatures from -55°C to +125°C and survive thermal shock cycles that crack plastic packages, making CD54AC04F3A suitable for avionics and satellite signal-conditioning boards.
How does the AC-series family of CD54AC04F3A compare to HC-series inverters for high-speed clock buffering?
The AC (Advanced CMOS) series of CD54AC04F3A achieves propagation delays under 10 ns at 5 V, compared to 20–25 ns typical for HC-series devices, enabling clock buffering and signal inversion at frequencies above 50 MHz. The AC series also provides 24 mA output drive versus 4–6 mA for HC, reducing voltage drooping when driving 50 pF bus capacitances across the 6 inverter channels simultaneously.
