• 74HC393 Dual 4-bit Binary Ripple Counter - 74393

74HC393 Dual 4-bit Binary Ripple Counter - 74393

  • RM1.80

  • Product Code: 74HC393N
  • Availability: In Stock

The ’HC393 devices contain eight flip-flops and additional gating to implement two individual 4-bit counters in a single package. These devices comprise two independent 4-bit binary counters, each having a clear (CLR) and a clock (CLK) input. N-bit binary counters can be implemented with each package, providing the capability of divide by 256.

The ’HC393 devices have parallel outputs from each counter stage so that any submultiple of the input count frequency is available for system timing signals.
