Working Principles

The CD74HC164M is a shift register that converts serial data input into parallel output. It operates by shifting the data bits through the register on each clock pulse. The parallel data inputs are loaded into the register when the Shift/Load (SH/LD) input is activated. The Master Reset (MR) input clears the register to its initial state.

Detailed Application Field Plans

The CD74HC164M can be used in various applications, including:

1. LED Displays: The shift register can control multiple LEDs by converting serial data into parallel output, enabling dynamic display patterns.
2. Serial Data Communication: It can be used in serial communication systems to convert serial data streams into parallel data for further processing.
3. Data Storage: The shift register can be utilized as a temporary storage device for small amounts of data in microcontroller-based systems.

Detailed and Complete Alternative Models

Some alternative models to the CD74HC164M include:

1. 74HC164: Similar functionality with slightly different pin configuration.
2. SN74HC164: Equivalent shift register from a different manufacturer.
3. CD4015: Dual 4-bit static shift register with similar characteristics.

These alternative models offer similar features and can be used as substitutes depending on specific requirements.
