The MC74HC74ADG is a positive-edge-triggered flip-flop. It stores a single bit of data and can be set or reset independently using the SET (PRE) and RESET (CLR) inputs, respectively. The stored data is available at the Q1 and Q2 outputs. On the rising edge of the clock signal (CLK), the input data (D1 and D2) is transferred to the outputs, following the state determined by the set and reset inputs.
The MC74HC74ADG finds applications in various digital systems where the storage and transfer of binary data are required. Some specific application fields include:
Some alternative models to the MC74HC74ADG include:
These alternative models offer similar functionality and can be used as substitutes depending on specific requirements.
