Overview
The HEF4017BT,653 from Nexperia USA Inc. is a 5-stage Johnson decade counter, designed to provide a robust and reliable counting solution in various electronic systems. This integrated circuit features 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 also includes 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 different counting applications.
