Decade Counter
The MC14017B is a five–stage Johnson decade counter with built–in code
converter. High speed operation and spike–free outputs are obtained by use
of a Johnson decade counter design. The ten decoded outputs are normally
low, and go high only at their appropriate decimal 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 decade counter or
decimal decode display applications.
• Fully Static Operation
• DC Clock Input Circuit Allows Slow Rise Times
• Carry Out Output for Cascading
• Divide–by–N Counting
• 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 CD4017B
