Frequently Asked Questions
What is the maximum operating frequency of the CD74HC112NS?
The CD74HC112NS operates at a maximum clock frequency of 4 MHz at nominal supply voltage with a 15 pF load capacitance. This makes it suitable for low to medium speed sequential logic designs such as counters, frequency dividers, and registered state machines in CMOS digital systems.
What package does the CD74HC112NS come in?
The CD74HC112NS is housed in a 16-pin small outline package (JEDEC code R-PDSO-G16), suitable for surface-mount PCB assembly. It carries a JEDEC-609 e4 rating and a Pbfree designation confirming RoHS-compliant lead-free construction for use in regulated markets.
Does the CD74HC112NS include preset and clear inputs?
Yes, the CD74HC112NS dual J-K flip-flop includes independent asynchronous preset and clear inputs on each flip-flop. This allows direct initialization and reset of each flip-flop independently of the clock edge, enabling flexible control of sequential circuit initial states.
What are typical applications for the CD74HC112NS?
Typical applications include binary counters, frequency dividers, toggle flip-flops, data synchronizers, edge detectors, and sequential state machine registers in digital control systems. Its compact 16-pin SOP package and low power consumption make it popular in consumer electronics and embedded system designs.
How does the CD74HC112NS compare to other J-K flip-flop variants?
The CD74HC112NS is in the HC/UH CMOS family offering lower power consumption and wider supply voltage range compared to older TTL families. Its 4 MHz maximum frequency is lower than faster HC devices like the CD74HC107M (20 MHz), making it better suited for low-frequency, low-power applications where energy efficiency is the priority.
