Programmable divide-by-n counter
HEF4059B
LSI
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.
