HD74HC4020 - 14-stage Binary Counter

General Description

The HD74HC4020 is a 14 stage counter.

This device is incremented on the falling edge (negative transition) of the input clock, and all its output is reset to a low level by applying a logical high on its reset input.

Key Features

  • High Speed Operation: tpd (Clock to Q1) = 14 ns typ (CL = 50 pF).
  • High Output Current: Fanout of 10 LSTTL Loads.
  • Wide Operating Voltage: VCC = 2 to 6 V.
  • Low Input Current: 1 µA max.
  • Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C).
  • Ordering Information Part Name Package Type Package Code (Previous Code) Package Abbreviation HD74HC4020P DILP-16 pin PRDP0016AE-B (DP-16FV) P HD74HC4020FPEL SOP-16 pin (JEITA) PRSP00.
