Working Principles

The CD74HC112MT is a dual J-K flip-flop that stores and manipulates binary data. Each flip-flop has two inputs, J and K, which control the state of the flip-flop based on the clock input. The clock input determines when the flip-flop will read the values of J and K and update its output accordingly. The clear input allows for resetting the flip-flop to a known state, while the preset input enables setting the flip-flop to a specific value.

Detailed Application Field Plans

The CD74HC112MT can be used in various digital logic applications, including but not limited to: - Counters and frequency dividers - Shift registers - Data storage and retrieval systems - Control circuits - Memory address decoding
