GENERAL DESCRIPTION
The 74HC/HCT4059 are high-speed Si-gate
CMOS devices and are pin compatible with the “4059” of the “4000B” series. They are specified in compliance with JEDEC standard no. 7A.
The 74HC/HCT4059 are divide-by-n counters which can be programmed to divide an input frequency by any number (n) from 3 to 15 999. There are four operating modes, timer, divide-by-n, divide-by-10 000 and master preset, which are defined by the mode select inputs (Ka to Kc) and the latch enable input (LE) as shown in the Function table.
The complete counter consists of a first counting stage, an int...
