What are the key features of CD54AC05F3A?
- Six independent open-drain inverter channels allowing wired-AND bus configurations and voltage level translation up to external pull-up voltage
- 24 mA open-drain output sink capability supporting direct LED or relay drive without external buffer transistors
- Military-grade ceramic DIP package providing superior thermal stability and reliability from -55 °C to +125 °C
- AC logic family achieving high-speed switching with 50 pF rated load capacitance for demanding signal integrity requirements
What is CD54AC05F3A used for?
The CD54AC05F3A is ideal for wired-AND bus arbitration in military avionics and ruggedized industrial control systems where open-drain outputs from multiple drivers share a common signal line pulled to a higher voltage rail. Its ceramic 14-Pin DIP package withstands the wide temperature range from -55 °C to +125 °C needed in harsh environment data bus interfaces. The 6-channel configuration also makes it efficient for active-low enable signal generation and voltage level shifting between 1.5 V logic and 5 V peripherals.

Frequently Asked Questions
What open-drain sink current can the CD54AC05F3A deliver and which loads can it drive directly?
Each output channel of the CD54AC05F3A sinks up to 24 mA, sufficient to drive a standard 5 mm LED at 20 mA through a 150 Ω series resistor on a 5 V pull-up, or to interface with a small signal relay coil rated at 12 mA to 20 mA, without requiring an additional driver transistor.
How does the CD54AC05F3A support wired-AND bus implementations in a multi-driver system?
Open-drain outputs from multiple CD54AC05F3A channels can be tied together on a shared bus line with a single 10 kΩ pull-up resistor to Vcc. Any active-low channel pulling to GND dominates, implementing wired-AND logic. This topology is common in I2C-compatible buses and interrupt lines where 8 or more sources share one wire in systems operating at 3.3 V or 5 V.
What temperature range and package type make the CD54AC05F3A suitable for harsh military environments?
The CD54AC05F3A is housed in a ceramic 14-Pin DIP (CDIP) rated from -55 °C to +125 °C. The hermetic ceramic package prevents moisture ingress that would degrade reliability in military avionics, satellite ground support equipment, and automotive under-hood environments exceeding the -40 °C to +85 °C rating of commercial plastic DIP parts.
When is the CD54AC05F3A a better alternative to a standard 74AC05 or 74HC05 in a level-translation design?
The CD54AC05F3A delivers the same 24 mA open-drain sink as the 74AC05 but with a military-qualified ceramic package rated to 125 °C and tested to MIL-STD conditions. For a 3.3 V logic source driving a 5 V bus through a 4.7 kΩ pull-up, the open-drain output level-shifts passively — no dedicated translator IC needed — saving board space and at least 1 component per channel in a 6-inverter design.
