SNJ54HC4020FK 14-BIT ASYNCHRONOUS BINARY COUNTERS

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.
