15. MR (Master Reset Input)
16. VDD (Supply Voltage)

Functional Features

• Serial-In, Parallel-Out (SIPO): The CD40194BPWRE4 can receive data serially through the SER pin and output it in parallel through the QA to QH pins.
• Asynchronous Reset: The SRCLR pin allows for clearing the shift register asynchronously, regardless of clock signals.
• Master Reset: The MR pin provides a master reset function that clears all outputs and resets the shift register.

Advantages and Disadvantages

Advantages

• Versatile shift register with multiple parallel outputs
• Wide operating voltage range
• Can be used in various applications requiring data storage and transfer

Disadvantages

• Limited number of parallel outputs (8 in total)
• Not suitable for applications requiring a large number of parallel outputs

Working Principles

The CD40194BPWRE4 operates by receiving serial data through the SER pin. On each rising edge of the CLK input, the received data is shifted into the shift register. When the RCLK input is triggered, the stored data is latched and available at the parallel outputs QA to QH. The SRCLR input can be used to clear the shift register asynchronously, while the MR input provides a master reset function.

Detailed Application Field Plans

The CD40194BPWRE4 can be used in various applications, including:

1. Data storage and retrieval systems
2. Serial-to-parallel data conversion
3. LED matrix control
4. Digital displays
5. Shift register-based counters
