How to Preset the CD74HC/HCT4059 to Desired
梅N
The value N is determined as follows:
(EQ. 1)
N = (MODE鈥? (1000 x Decade 5 Preset + 100 x Decade 4
Preset + 10 x Decade 3 Preset + 1 x Decade 2 Preset) +
Decade 1 Preset
鈥?/div>
MODE = First counting section divider (10, 8, 5, 4 or 2)
N
Preset Value = Mode
Example:
N = 8479, Mode = 5
(EQ. 2)
To calculate preset values for any N count, divide the N
count by the Mode. The resultant is the corresponding
preset values of the 5th through 2nd decade with the
remainder being equal to the 1st decade value.
Mode Select = 5

NOTE:
To verify the results, use Equation 1:
N = 5 (1000 x 1 + 100 x 6 + 10 x 9 + 1 x 5) + 4
N = 8479
