Overview
The HEF4017BT,652 is a 5-stage Johnson decade counter produced by Nexperia USA Inc. This integrated circuit is designed to provide ten spike-free decoded active HIGH outputs (Q0 to Q9) and an active LOW carry output from the most significant flip-flop (Q5-9). It features active HIGH and active LOW clock inputs (CP0, CP1) and an overriding asynchronous master reset input (MR). The counter is advanced by specific transitions at the clock inputs, making it versatile for various counting applications.
