1. general description the 74hc4020-q100; 74hct4020-q100 are 14-s tage binary ripple counters with a clock input (cp ), an overriding asynchronous master reset input (mr) and 12 buffered parallel outputs (q0, and q3 to q13). 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.. 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 ? input levels: ? for 74hc4020-q100: cmos level ? for 74hct4020-q100: ttl level ? 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 ? control counters 74hc4020-q100; 74hct4020-q100 14-stage binary ripple counter rev. 1 ? 23 may 2013 product data sheet
