SN74HC4020D - 14-Bit Asynchronous Binary Counters

Download the SN74HC4020D datasheet PDF. This datasheet also covers the SN74HC4020 variant, as both devices belong to the same 14-bit asynchronous binary counters family and are provided as variant models within a single manufacturer 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 2.
