DESCRIPTION
The HEF4059B is a divide-by-n counter which can be programmed to divide an input frequency by any number n from 3 to 15 999. The output signal is a one clock-cycle wide pulse and occurs at a rate equal to the input frequency divided by n. The single output (O) has TTL drive capability. The down counter is preset by means of
16 jam inputs (J1 to J16); continued on next page.
