Overview
74HC4020; 74HCT4020 14-stage binary ripple counter Rev.
8 — 7 September 2021 Product data sheet 1.
General description The 74HC4020; 74HCT4020 is a 14-stage binary ripple counter with a clock input (CP), an overriding asynchronous master reset input (MR) and 12 buffered parallel outputs (Q0, and Q3 to Q13).
The counter advances on the HIGH-to-LOW transition of CP.
A HIGH on MR clears all counter stages and forces all outputs LOW, independent of the state of CP.
Each counter stage is a static toggle flip-flop.
Inputs include clamp diodes.
This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
