Frequently Asked Questions
What is the maximum operating frequency and load capacitance specification of the CD54HC112F3A?
The CD54HC112F3A operates at up to 4MHz with a 15pF load capacitance, making it suitable for low-to-medium speed digital state machines, frequency dividers, and clock synchronization circuits within the HC/UH CMOS logic family. The 6mA maximum sink current (I_OL) supports standard logic-level loads.
Why is the CD54HC112F3A in a ceramic 16-pin DIP package preferred for military and aerospace applications?
The CD54HC112F3A uses a ceramic GDIP-T16 package rated JESD-609 code e0, which provides superior hermetic sealing and thermal conductivity compared to plastic packages. This makes it the preferred choice for aerospace avionics, military radar, and satellite electronics where temperature extremes, humidity, and vibration would degrade standard plastic DIP components over time.
How can a designer use CD54HC112F3A's independent set and reset pins to build a toggle flip-flop or frequency divider?
By connecting both J and K inputs of one CD54HC112F3A flip-flop to logic HIGH and applying a clock signal to the negative-edge trigger input, the Q output toggles on every falling clock edge, creating a divide-by-2 frequency divider up to 4MHz. The independent active-low set and reset pins allow forced initialization to a known state, which is essential in 16-bit counter designs and state machine startup sequences.
