The ’HC4040 and ’HCT4040 are 14-stage ripple-carry
binary counters. All counter stages are master-slave flip-
flops. The state of the stage advances one count on the
negative clock transition of each input pulse; a high voltage
level on the MR line resets all counters to their zero state. All
inputs and outputs are buffered.
