PARALLEL-LOAD 8-BIT SHIFT REGISTERS
The 74LS166 is a high-speed 8-bit parallel-in/parallel-out shift register. It is a member of the 74LS family of logic ICs, which are low-power Schottky TTL devices. Description: The 74LS166 is an 8-bit parallel-in/parallel-out shift register. It has a serial input (SI) and a serial output (SO) for cascading multiple registers. It also has a clock input (CP) and a clear input (CLR) for controlling the shift register. The register can be cleared by applying a low logic level to the CLR input. Features: 8-bit parallel-in/parallel-out shift register Low-power Schottky TTL Serial input (SI) and serial output (SO) Clock input (CP) Clear input (CLR) 16-pin DIP package Applications: The 74LS166 is commonly used in applications such as data storage, data transfer, and data manipulation. It can be used to store and transfer data between two devices, or to manipulate data within a single device. It is also used in digital logic circuits, such as counters and shift registers.
