 

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 e ight 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 Two Low–power TTL Loads or One Low–power

Schottky TTL Load Over the Rated Temperature Range

• Pin–for–Pin Replacement for CD4022B

• Triple Diode Protection on All Inputs

#Data labelled “Typ” is not to be used for design purposes but is intended as an indication of the IC’s potential performance. **The formulas given are for the typical characteristics only at 25_C. †To calculate total supply current at loads other than 50 pF:

IT(CL) = IT(50 pF) + (CL – 50) Vfk

where: IT is in µA (per package), CL in pF, V = (VDD – VSS) in volts, f in kHz is input frequency, and k = 0.00125.

This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, Vin and V

out

should be constrained to the range VSS ≤ (Vin or V

out

) ≤ VDD.

Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must be left open.
