74HC4017; 74HCT4017
Johnson decade counter with 10 decoded outputs
Rev. 4 — 10 December 2013
Product data sheet
1. General description
The 74HC4017; 74HCT4017 is a 5-stage Johnson decade counter with 10 decoded
outputs (Q0 to Q9), an output from the most significant flip-flop (Q5-9), two clock inputs
(CP0 and CP1) and an overriding asynchronous master reset input (MR). The counter is
advanced by either a LOW-to-HIGH transition at CP0 while CP1 is LOW or a
HIGH-to-LOW transition at CP1 while CP0 is HIGH. When cascading counters, the Q5-9
output, which is LOW while the counter is in states 5, 6, 7, 8 and 9, can be used to drive
the CP0 input of the next counter. A HIGH on MR resets the counter to zero (Q0 = Q5-9 =
HIGH; Q1 to Q9 = LOW) independent of the clock inputs (CP0 and CP1). 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. Inputs include clamp
diodes. This enables the use of current limiting resistors to interface inputs to voltages in
excess of V
CC
.

(1) This is not a supply pin. The substrate is attached to this
pad using conductive die attach material. There is no
electrical or mechanical requirement to solder this pad.
However, if it is soldered, the solder land should remain
floating or be connected to GND.
