CD4018BMS Overview
CD4018BMS types consist of 5 Johnson-Counter stages, buffered Q outputs from each stage, and counter preset control gating. CLOCK, RESET, DATA, PRESET ENABLE, and 5 individual JAM inputs are provided. Divide by 10, 8, 6, 4, or 2 counter configurations can be implemented by feeding the Q5, Q4, Q3, Q2, Q1 signals, respectively, back to the DATA input.
