Working Principles

The SN74ABT374APWG4 operates based on the principles of D-type flip-flops. The CP input serves as the clock signal, which triggers the flip-flops to latch the data inputs (D0-D7) on the rising edge of the clock. The master reset (MR) input allows all flip-flops to be asynchronously reset when activated. The outputs (Q0-Q7) reflect the state of the corresponding data inputs after each clock cycle. The 3-state outputs can be enabled or disabled using control signals, allowing the device to drive or float the output lines.
