异步 14 位二进制计数器

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. • Wide Operating Voltage Range of 2 V to 6 V\n• Outputs Can Drive Up To 10 LSTTL Loads\n• Low Power Consumption, 80-µA Max ICC\n• Typical tpd = 12 ns\n• ±4-mA Output Drive at 5 V\n• Low Input Current of 1 µA Max;
