Disadvantages: - Limited number of parallel outputs (8 bits). - Requires external clock signals for proper functioning.

Working Principles

The CD74HCT4094M96 operates based on the principle of shifting data bits through its internal shift register. The serial data input (SER) receives data bit by bit, which is then shifted into the shift register upon each rising edge of the shift register clock (SRCLK). The register clock (RCLK) controls the parallel loading of the data from the shift register to the parallel outputs (Q0-Q7).

Detailed Application Field Plans

The CD74HCT4094M96 finds applications in various fields, including:

1. LED Displays: It can be used to control LED displays, enabling the sequential illumination of multiple LEDs.
2. Data Storage: The shift register functionality allows for temporary data storage in applications such as data logging or buffering.
3. Serial-to-Parallel Conversion: It is commonly employed to convert serial data streams into parallel data formats.
