Frequently Asked Questions
How many independent OR gate functions does the CD54AC32F3A provide, and what are the output drive specifications?
The CD54AC32F3A contains 4 independent 2-input OR gate functions in a single 14-pin package. Each output can sink up to 24 mA and drive loads with up to 50 pF capacitance, making it capable of directly driving TTL-compatible logic lines and short PCB traces at high switching speeds typical of the AC CMOS logic family.
Why is the ceramic DIP package of the CD54AC32F3A preferred in military and harsh-environment logic designs?
The ceramic 14-pin DIP package of the CD54AC32F3A provides hermetic sealing, which prevents moisture ingress and corrosion in humid or contaminated environments. This is critical for military avionics, space payloads, and industrial control systems where standard plastic SOIC packages would fail under temperature cycling or moisture exposure, and where long-term component availability over decades is required.
When is the CD54AC32F3A a better choice than an LSTTL quad OR gate for a 5 V logic board?
The CD54AC32F3A from the AC CMOS family offers lower power consumption at static conditions than LSTTL gates, while still providing 24 mA output drive compatible with TTL logic levels at 5 V. For designs that need the ceramic DIP format for reliability or that require CMOS noise margins and lower ICC at high logic switching rates, the AC32 is preferred over older LSTTL equivalents.
