Johnson decade counter with 10 decoded outputs
74HC/HCT4017
FEATURES
Output capability: standard
I
CC
category: MSI
GENERAL DESCRIPTION
The 74HC/HCT4017 are high-speed Si-gate CMOS
devices and are pin compatible with the “4017” of the
“4000B” series. They are specified in compliance with
JEDEC standard no. 7A.
The 74HC/HCT4017 are 5-stage Johnson decade
counters with 10 decoded active HIGH outputs (Q
0
to Q
9
),
an active LOW output from the most significant flip-flop
(Q
5-9
), active HIGH and active LOW clock inputs (CP
0
and
CP
1
) and an overriding asynchronous master reset input
(MR).
The counter is advanced by either a LOW-to-HIGH
transition at CP
0
while CP
1
is LOW or a HIGH-to-LOW
transition at CP
1
while CP
0
is HIGH (see also function
table).
When cascading counters, the Q
5-9
output, which is LOW
while the counter is in states 5, 6, 7, 8 and 9, can be used
to drive the CP
0
input of the next counter.
A HIGH on MR resets the counter to zero
(Q
0
= Q
5-9
= HIGH; Q
1
to Q
9
= LOW) independent of the
clock inputs (CP
0
and CP
1
).
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.
