1. general description the 74hc4024-q100 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 out puts low, independent of the state of cp . each counter stage is a static toggle flip-flop. schm itt-trigger action in the clock input makes the circuit highly tolerant to slower clock rise a nd fall times. inputs include clamp diodes. this enables the use of current limiting resistors to interface inputs to voltages in excess of v cc . this product has been qualified to the automotive electronics council (aec) standard q100 (grade 1) and is suitable for use in automotive applications. 2. features and benefits ? automotive product qualif ication in accordance with aec-q100 (grade 1) ? specified from ? 40 ? c to +85 ? c and from ? 40 ? c to +125 ? c ? low power dissipation ? complies with jedec standard no. 7a ? esd protection: ? mil-std-883, method 3015 exceeds 2000 v ? hbm jesd22-a114f exceeds 2000 v ? mm jesd22-a115-a exceeds 200 v (c = 200 pf, r = 0 ? ) ? multiple package options 3. applications ? frequency dividing circuits ? time delay circuits 74hc4024-q100 7-stage binary ripple counter rev. 1 ? 27 november 2013 product data sheet
