The CD74HC166MT is an integrated-circuit (IC) component, commonly known as a 8-bit parallel-in serial-out (PISO) shift register. It is part of the 74HC series, which is a widely-used family of high-speed CMOS logic ICs. This particular IC is manufactured by Texas Instruments.
The CD74HC166MT has multiple key features that make it useful in various applications. Here is an overview of its main attributes:
1. Shift Register Configuration: The IC consists of an 8-bit shift register that can store data in 8 individual flip-flops. It allows parallel loading of data into the flip-flops and subsequent serial shifting out of the data. This makes it ideal for serial data transfer applications.
2. Serial and Parallel Inputs: The CD74HC166MT offers a parallel data input (DS) which allows direct loading of data into the 8 flip-flops simultaneously. It also has a serial input (SI), enabling serial data entry. This flexibility allows for easy integration into different systems.
3. Serial Output: The IC provides a serial output (QH') for cascading multiple CD74HC166MTs in a daisy-chain configuration. This allows for expanding the number of available shift registers, enabling the transfer of large amounts of data.
4. Synchronous Operation: The CD74HC166MT operates synchronously, meaning that data is loaded and shifted based on clock signals
