HD74HC4024
7-stage Binary Counter
REJ03D0325-0300 Rev.3.00 Mar 30, 2006
Description
The HD74HC4024 is a 7-stage counter. This device is incremented on the falling edge (negative transition) of the input clock, and all its output is reset to a low level by applying a logical high on its reset input.
Features
