TC4017BP/TC4017BF Decade Counter/Divider

TC4017BP/BF is decimal Johnson counter consisting of 5 stage

D-type flip-flop equipped with the decoder to convert the output

to decimal.

Depending on the number of count pulses fed to CLOCK or

CLOCK INHIBIT one output among 10 output lines “Q0” through

“Q9” becomes “H” level.

The counter advances its state at rising edge of CLOCK

(CLOCK INHIBIT = “L”) or falling edge of CLOCK INHIBIT

(CLOCK = “H”). RESET input to “H” level resets the counter to

Q0 = “H” and Q1 through Q9 = “L” regardless of CLOCK and

CLOCK INHIBIT.
