The DM54LS164J883C accepts serial data at the input and shifts it through the register on each positive-going clock transition. The data is available in parallel form at the eight outputs. An asynchronous clear input allows for resetting the register to all zeros. 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 ensures hermeticity and resistance to environmental stresses. This part is widely used in systems where data is transmitted serially and needs to be accessed in parallel, such as display drivers and remote control systems.
