The DM54LS374J/883B consists of eight D-type flip-flops. Data at the D inputs is transferred to the Q outputs on the positive-going transition of the clock pulse. The three-state outputs can be enabled or disabled using the output enable input. When the output enable is high, the outputs are in a high-impedance state. The device operates from a standard 5V power supply. The Low Power Schottky technology minimizes power consumption while maintaining good speed characteristics. The ceramic package provides excellent hermeticity and resistance to environmental stresses. This device is widely used in microprocessor systems, memory interfaces, and other applications requiring parallel data storage and retrieval.
