They are ideal for slowly changing or noisy signals. The count advances as the clock input becomes low on the falling-edge , this is indicated by the bar over the clock label. This is the usual clock behaviour of ripple counters and it means a counter output can directly drive the clock input of the next counter in a chain. For normal use connect QA to clockB to link the two sections, and connect the external clock signal to clockA. For normal operation at least one reset0 input should be low, making both high resets the counter to zero , QA-QD low. Note that the has a pair of reset9 inputs on pins 6 and 7, these reset the counter to nine so at least one of them must be low for counting to occur.

Motorola — datasheet pdf Is the count from 9 to 0 or is it? Want to Make a Ton of Money? Terminal count up pin 12 connects to clock pulse up pin 5 of the next stage.
