HEF4017B datasheet



The HEF4017B 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 masterreset 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).

Automatic counter code correction is providedby 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 VDDpower supply range of 3 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input.



1. Automatic counter correction

2. Tolerant of slow clock rise and fall times

3. Fully static operation

4. 5 V, 10 V, and 15 V parametric ratings

5. Standardized symmetrical output characteristics
