Description
NC = NO CONNECTION
CD4020BMS - 14 Stage CD4024BMS - 7 Stage CD4040BMS - 12 Stage CD4020BMS, CD4024BMS, and CD4040BMS are ripplecarry 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 the CD4040BMS is supplied in these 14 lead outline packages:
