SN54HC4020J

SN54HC4020, SN74HC4020 SCLS158F – DECEMBER 1982 – REVISED FEBRUARY 2022 SNx4HC4020 14-Bit Asynchronous Binary Counters 1 Features 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 2 Description 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.
