description/ordering informationThe ’HC4020 devices are 14-stage binary ripple-carry counters that advance on the negative-going edge of the
clock pulse. The counters are reset to zero (all outputs low) independently of the clock (CLK) input when the
clear (CLR) input goes high.
ORDERING INFORMATION†Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are
available at www.ti.com/sc/package.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
