Decade Counter
The MC14017B is a fiveâstage Johnson decade counter with builtâin code
converter. High speed operation and spikeâfree 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 positiveâgoing 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
⢠DivideâbyâN Counting
⢠Supply Voltage Range = 3.0 Vdc to 18 Vdc
⢠Capable of Driving Two Lowâpower TTL Loads or One Lowâpower
Schottky TTL Load Over the Rated Temperature Range
⢠PinâforâPin Replacement for CD4017B
ÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃà ⢠Triple Diode Protection on All Inputs
