The MM74HC165M is an integrated circuit (IC) component that belongs to the 74HC family of high-speed CMOS devices. It functions as a parallel-in/serial-out (PISO) shift register, which allows for the conversion of parallel data to serial data. Below are the key features of the MM74HC165M:
1. High-speed operation: The MM74HC165M operates at high-speed with a maximum clock frequency of 33 MHz, enabling rapid data transmission.
2. 8-bit parallel input: It has 8 parallel inputs (A0-A7) that can receive data simultaneously. These inputs can be connected to switches, sensors, or any other digital devices to capture data in a parallel format.
3. Serial output: The MM74HC165M has a serial output pin (Q7) that outputs the captured data in a serialized manner, one bit at a time. This feature is useful for cascading multiple ICs to receive data from multiple parallel sources sequentially.
4. Cascadable: It supports cascading, allowing multiple MM74HC165M ICs to be connected in series to provide an expanded number of parallel inputs. By connecting the output of one IC to the input of another, a larger number of parallel inputs can be accommodated.
5. Shift register functionality: The IC incorporates an 8-bit shift register that facilitates the conversion of parallel input data to serial output data
