Working Principles

The SN74HC259DR is a serial-to-parallel converter with latched outputs. It receives serial data through the A, B, and C inputs and converts it into parallel output on Q0-Q7. The conversion occurs on the rising edge of the clock pulse (CP) signal. The output data remains latched until a new clock pulse is received or a master reset (MR) signal is activated. The output enable (OE) signal controls whether the output data is enabled or disabled.

Detailed Application Field Plans

1. Data storage and retrieval systems
2. Address decoding in memory modules
3. Multiplexing and demultiplexing applications
4. Parallel-to-serial data conversion
5. Control and interface circuits in microcontroller-based systems
