DESCRIPTION
The HEF4017B is a 5-stage Johnson decade counter with
ten spike-free decoded active HIGH outputs (O
active LOW output from the most significant flip-flop (O
active HIGH and active LOW clock inputs (CP
an overriding asynchronous master reset input (MR).
The counter is advanced by either a LOW to HIGH

while the counter is in states 5, 6, 7, 8 and 9, can be used
to drive the CP

Automatic code correction of the counter is provided by an
internal circuit: following any illegal code the counter
returns to a proper counting mode within 11 clock pulses.
Schmitt-trigger action in the clock input makes the circuit
highly tolerant to slower clock rise and fall times.
