MC14022B
Octal Counter
The MC14022B is a four–stage Johnson octal counter with built–in
code converter. High–speed operation and spike–free outputs are
obtained by use of a Johnson octal counter design. The eight decoded
outputs are normally low, and go high only at their appropriate octal
time period. The output changes occur on the positive–going edge of
the clock pulse. This part can be used in frequency division
applications as well as octal counter or octal decode display
applications.
• Fully Static Operation
• DC Clock Input Circuit Allows Slow Rise Times
• Carry Out Output for Cascading
• Supply Voltage Range = 3.0 Vdc to 18 Vdc
• Capable of Driving T wo Low–power TTL Loads or One Low–power
Schottky TTL Load Over the Rated T emperature Range
• Pin–for–Pin Replacement for CD4022B
• Triple Diode Protection on All Inputs

3. Data labelled “Typ” is not to be used for design purposes but is intended as an indication of the IC’s potential performance.
4. The formulas given are for the typical characteristics only at 25_C.
5. To calculate total supply current at loads other than 50 pF:
I
) = IT(50 pF) + (CL – 50) Vfk
T(CL
where: I
is in µA (per package), CL in pF, V = (VDD – VSS) in volts, f in kHz is input frequency, and k = 0.00125.
