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 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
MAXIMUM RATINGS (Voltages Referenced to VSS) (Note 1.)

1. Maximum Ratings are those values beyond which damage to the device
may occur.
2. Temperature Derating:
Plastic “P and D/DW” Packages: – 7.0 mW/_C From 65_C To 125_C
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
v vhigh–impedance circuit. For proper operation, Vin and Vout should be constrained
to the range VSS (Vin or Vout) 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.
