Description
The Harris CD74HC4024 and CD74HCT4024 are 7-stage
ripple-carry binary counters. All counter stages are masterslave flip-flops. The state of the stage advances one count
on the negative 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.
