Disadvantages: - Limited number of parallel outputs (4 in this case). - Requires an external clock signal for proper operation.

Working Principles

The SN74HC164DE4 is a synchronous shift register that operates based on the rising edge of the clock signal. When the clock input (A) receives a rising edge, the data present at the serial input (B-H) is shifted into the register. The previously stored data is shifted to the next stage, and the last stage's output is available at the parallel output pins (QH'-QF').

Detailed Application Field Plans

The SN74HC164DE4 can be used in various applications, including:

  1. LED Matrix Displays: The shift register can control multiple LEDs by converting serial data from a microcontroller into parallel output signals.
  2. Serial-to-Parallel Conversion: It can be used to convert serial data from sensors or communication interfaces into parallel format for further processing.
  3. Data Storage: The shift register can store data temporarily before it is processed by other components in a system.

Detailed and Complete Alternative Models

  1. 74HC164: Similar functionality but operates at a lower voltage range (2V to 5.5V).
  2. CD74HC164: Equivalent functionality with a different package type (DIP-14).

These alternative models provide similar features and can be used as replacements for the SN74HC164DE4 depending on specific requirements.
