Working Principles

The IDT74FCT163344APAG is a synchronous counter that increments its count value on the rising edge of the clock signal. The counter can be cleared asynchronously using the CLR input, which sets the count value to zero. The output enable (OE) input allows the outputs to be tri-stated, effectively disconnecting them from the circuit.

Detailed Application Field Plans

  • Digital frequency dividers
  • Event counters
  • Timekeeping circuits
  • Address generation in memory systems
  • Industrial automation control systems

Alternative Models

  • SN74FCT163344APAG
  • MC74FCT163344APAG
  • CD74FCT163344APAG
  • 74ACT163344APAG

These alternative models offer similar functionality and can be used as replacements for the IDT74FCT163344APAG.
