SN74HC4020DR Datasheet PDF - TI

●description/ordering information

●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

● Outputs Can Drive Up To 10 LSTTL Loads

● Low Power Consumption, 80-µA Max ICC

● Typical tpd = 12 ns

● ±4-mA Output Drive at 5 V

● Low Input Current of 1 µA Max
