HEF4017B-Q100
5-stage Johnson decade counter
Rev. 1 — 4 June 2014
Product data sheet
1. General description
The HEF4017B-Q100 is a 5-stage Johnson decade counter with ten spike-free decoded
active HIGH outputs (Q0 to Q9), an active LOW carry output from the most significant
flip-flop (Q5-9), active HIGH and active LOW clock inputs (CP0, 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 (see Table 3).
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, CP1).
Automatic counter code correction 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 makes the clock inputs highly tolerant of slower rise and fall times.
It operates over a recommended VDD power supply range of 3 V to 15 V referenced to VSS
(usually ground). Unused inputs must be connected to VDD, VSS, or another input.
This product has been qualified to the Automotive Electronics Council (AEC) standard
Q100 (Grade 1) and is suitable for use in automotive applications.
