Working Principles

The 74HC161PW,112 is a 4-bit synchronous binary counter. It operates using a common clock input (CP) and counts up or down based on the clock pulses. The counter can be cleared to zero using the master reset input (MR). Data can be loaded into the counter using the parallel enable input (PE), and the terminal count output (TC) indicates when the maximum count is reached. The outputs (QA, QB, QC, QD) represent the current count value.

Detailed Application Field Plans

  • Digital frequency dividers
  • Event counters
  • Time delay generators
  • Industrial automation systems
  • Communication equipment
  • Consumer electronics
