Functional Features

• The MM74HC164MX is designed to shift in serial data from the DS input and provide parallel data output on the QH' to QA pins.
• It operates on a positive edge-triggered clock pulse, which allows for synchronized data transfer.
• The IC can be cascaded to form longer shift registers by connecting the serial output (QH) of one IC to the serial input (DS) of the next IC.

Advantages and Disadvantages

Advantages: - High-speed operation due to CMOS technology - Wide operating voltage range - Compact SOIC package for space-saving designs - Easy cascading for expanding the number of bits

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

Working Principles

The MM74HC164MX works based on the principle of shifting data in a serial-in, parallel-out manner. When a clock pulse is applied to the CP input, the data at the DS input is shifted into the first flip-flop stage. On each subsequent clock pulse, the data is shifted through the flip-flops until it reaches the last stage. The parallel outputs then reflect the shifted data.

Detailed Application Field Plans

The MM74HC164MX can be used in various applications, including:

1. Data communication systems
2. Serial-to-parallel data conversion
3. LED matrix displays
4. Shift register-based counters
5. Control and interface circuits
