description/ordering information
NC − No internal connection
The ’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.
