The 74HCT166N,652 is a popular integrated circuit (IC) component manufactured by Nexperia, a leading semiconductor company. It belongs to the 74HCT series, which is a high-speed CMOS (Complementary Metal-Oxide-Semiconductor) device family. The 74HCT166N,652, specifically, is an 8-bit parallel-in/serial-out (PI/SO) shift register IC. Here is an overview of this component and its key features:
1. Functionality: The 74HCT166N,652 is primarily used as a shift register, which allows data to be shifted in parallel and then shifted out serially. It consists of eight data input pins (D0-D7), a parallel load input pin (PL), a clock input pin (CP), a clock enable input pin (CE), a reset input pin (MR), and a serial output pin (QH).
2. Bit Storage: The IC can store data in its internal eight-stage shift register, providing a 8-bit parallel-to-serial conversion.
3. Parallel Load Operation: By asserting a HIGH signal on the Parallel Load (PL) pin while the Clock Enable (CE) pin is LOW, the data present on the Data Input (D0-D7) pins can be loaded in parallel into the shift register
