1. general description the 74hc4020; 74hct4020 are high-spe ed si-gate cmos devices and are pin compatible with the hef4020b series. they are specified in compliance with jedec standard no. 7a. the 74hc4020; 74hct4020 are 14-stage binary ripple counters with a clock input ( cp ), an overriding asynchronous master reset input (mr) and twelve parallel outputs (q0, 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. 2. features ? multiple package options ? complies with jedec standard no. 7a ? specified from ? 40 c to +85 c and from ? 40 c to +125 c 3. applications ? frequency dividing circuits ? time delay circuits ? control counters 4. ordering information 74hc4020; 74hct4020 14-stage binary ripple counter rev. 03 ? 20 january 2010 product data sheet table 1. ordering information type number package temperature range name description version 74hc4020n ? 40 c to +125 c dip16 plastic dual in-line package; 16 leads (300 mil) sot38-4 74hct4020n 74hc4020d ? 40 c to +125 c so16 plastic small outline package; 16 leads; body width 3.9 mm sot109-1 74hct4020d 74hc4020db ? 40 c to +125 c ssop16 plastic shrink small outline package; 16 leads; body width 5.3 mm sot338-1 74hct4020db
