CD74HC4024E Datasheet PDF - TI

Description

●The ’HC4024 and ’HCT4024 are 7-stage ripple-carry binary counters. All counter stages are master-slave 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.
