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 V_CC

.

2. Features and benefits

Definitions

Limiting values — Stress above one or more limiting values (as defined in

the Absolute Maximum Ratings System of IEC 60134) will cause permanent

damage to the device. Limiting values are stress ratings only and (proper)

operation of the device at these or any other conditions above those

given in the Recommended operating conditions section (if present) or the

Characteristics sections of this document is not warranted. Constant or

repeated exposure to limiting values will permanently and irreversibly affect

the quality and reliability of the device.
