Product Overview

The CD74HC4059E is a CMOS programmable high-speed Divide-by-N Counter with pin-compatible. This device can be programmed to divide an input frequency by any number "N" from 3 to 15999. The output signal is a pulse one clock cycle wide occurring at a rate equal to the input frequency divide by N. The down-counter is pre-set by means of 16 jam inputs. The three Mode-Select Inputs Ka, Kb and Kc determine the modulus ("divide-by" number) of the first and last counting sections in accordance with the truth table. Every time the first (fastest) counting section goes through one cycle, it reduces by 1 the number that has been pre-set (jammed) into the three decades of the intermediate counting section and the last counting section, which consists of flip-flops that are not needed for opening the first counting section.
  • Presettable down-counter
  • Fully static operation
  • Master pre-set initialization
  • Latchable N output
  • Balanced propagation delay and transition times
  • Significant power reduction compared to LSTTL logic ICs
