General description
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 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).

FEATUREs
■ Automatic counter correction
■ Tolerant of slow clock rise and fall times
■ Fully static operation
■ 5 V, 10 V, and 15 V parametric ratings
■ Standardized symmetrical output characteristics
■ Operates across the automotive temperature range −40 °C to +125 °C
■ Complies with JEDEC standard JESD 13-B
■ ESD protection:
   ◆ HBM JESD22-A114E exceeds 2000 V
   ◆ MM JESD22-A115-A exceeds 200 V

APPLICATIONs
■ Industrial and automotive
