1. General description

The 74HC4024 is a 7-stage binary ripple counter with a clock input (CP), an overriding

asynchronous master reset input (MR) and seven fully buffered parallel outputs (Q0 to Q6). The

counter advances on the HIGH-to-LOW transition of CP. A HIGH on MR clears all counter stages

and forces all outputs LOW, independent of the state of CP. Each counter stage is a static toggle

flip-flop. Schmitt-trigger action in the clock input makes the circuit highly tolerant to slower clock

rise and fall times. Inputs include clamp diodes. This enables the use of current limiting resistors to

interface inputs to voltages in excess of VCC.
