CD4024BMS Functional Diagram
Description
The CD4020BMS (14-stage), CD4024BMS (7-stage), and CD4040BMS (12-stage) are ripple carry binary counters. All counter stages are master-slave flip-flops. The state of a counter advances one count on the negative transition of each input pulse; a high level on the RESET line resets the counter to its all zeros state. Schmitt trigger action on the input-pulse line permits unlimited rise and fall times. All inputs and outputs are buffered. The CD4020BMS, CD4024BMS and CD4040BMS are supplied in these 14-lead outline packages: Braze Seal DIP H4W, H4Q and H4X; Frit Seal DIP H1F and H1B; and Ceramic Flatpack H6W and H3W.
Applications
- Control counters
- Timers
- Frequency dividers
- Time-delay circuits
