CD4020BMS, CD4024BMS, and CD4040BMS 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 the CD4040BMS is
