Working Principles
The DM74ALS174M is a positive-edge triggered flip-flop that stores a single bit of data. It operates synchronously with the rising edge of the clock pulse input (CP). The data input (D) is sampled and stored in the flip-flop when the clock pulse rises from low to high. The stored data is available at the output (Q) and its complementary output (Q').
The flip-flop can be cleared asynchronously by applying a low level signal to the clear input (CLR). This resets the flip-flop, forcing both Q and Q' outputs to a known state.
