The 74HC165PW,118 is a 8-bit parallel-in/serial-out shift register IC component. It is part of the 74HC series of high-speed CMOS integrated circuits. Here is an overview and key features of the 74HC165PW,118:
1. Introduction: The 74HC165PW,118 is designed to act as a parallel-input to serial-output converter. It can receive data in parallel format and shift it out in a serial format using a single clock input.
2. 8-bit Parallel Input: The IC has 8 parallel input lines (D0 to D7) that can accept data from external sources or other digital devices. These inputs are enabled by the parallel load input (PL) signal.
3. Serial Output: The IC provides a serial output (Q7S) that sequentially shifts out the data from the parallel inputs. This output is synchronized with the internal shift clock.
4. Shift Clock Input: The shift clock input (CP) controls the shifting of data from parallel to serial output. When the shift clock signal transitions from LOW to HIGH, data on the parallel inputs is shifted to the serial output.
5. Serial Output Enable: The IC features a serial output enable input (OE) that allows for disabling the serial output Q7S. When OE is HIGH, the serial output is disabled, hence stopping the shifting operation
