SN74HC4020 (ACTIVE) 14-Bit Asynchronous Binary Counters

14-Bit Asynchronous Binary Counters - SN74HC4020
Datasheet
 

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.

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
