Functional Features

  • Counter Mode: In this mode, the 74F169SC functions as a 4-bit binary counter. The parallel data inputs (P0-P3) are used to set the initial count value, and the clock pulse input (CP) increments the count on each rising edge.
  • Shift Register Mode: In this mode, the IC acts as a 4-bit shift register. The parallel data inputs (P0-P3) are loaded into the register, and subsequent clock pulses (CP) shift the data through the serial outputs (Q0-Q3).
  • Parallel Enable: The parallel enable input (PE) allows the user to control whether the parallel data inputs affect the counter or shift register operation.
  • Terminal Count: The terminal count output (TE) goes high when the counter reaches its maximum value, providing an indication that a full count cycle has been completed.

Advantages and Disadvantages

Advantages: - High-speed operation - Versatile functionality as both a counter and a shift register - Synchronous operation for precise timing - TTL-compatible input and output voltage levels

Disadvantages: - Limited number of stages (4 bits) - Requires external components for more complex applications

Working Principles

The 74F169SC operates based on synchronous logic principles. In counter mode, the clock pulse input (CP) triggers the incrementation of the counter by one on each rising edge. The parallel data inputs (P0-P3) allow the user to set the initial count value. In shift register mode, the parallel data inputs are loaded into the register, and subsequent clock pulses shift the data through the serial outputs.
