Working Principles

The SN74AS74ANG4 is a dual D-type positive-edge-triggered flip-flop. It stores digital information using two flip-flops, each capable of storing a single bit of data. The clock input triggers the transfer of data from the input pins (D1 and D2) to the corresponding flip-flops. The outputs (Q1 and Q2) reflect the stored data and can be used as inputs for other components or circuits.

The asynchronous clear input (CLR) allows for the simultaneous reset of both flip-flops, setting their outputs to a known state. This feature is useful for initializing the circuit or clearing stored data when required.
