Disadvantages: - Limited number of bits (8) - Requires an external clock signal

Working Principles

The MM74HC164N operates based on the principle of serial-in, parallel-out shifting. When a clock pulse is applied to the CLK input, the data at the SER input is shifted into the first flip-flop of the shift register. Subsequent clock pulses shift the data through the remaining flip-flops. The parallel outputs reflect the current state of the shift register.

Detailed Application Field Plans

The MM74HC164N can be used in various applications, including:

  1. LED Matrix Displays: It can be used to control the rows or columns of an LED matrix display, allowing for dynamic patterns and animations.
  2. Serial Data Transmission: It can convert serial data from a microcontroller or other devices into parallel data for further processing.
  3. Data Storage: It can be used as a temporary storage device for data that needs to be processed in parallel.
