Product data sheet
1. General description
The 74HT4020; 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. This device features reduced input threshold
levels to allow interfacing to TTL logic levels. Inputs also include clamp diodes, this
enables the use of current limiting resistors to interface inputs to voltages in excess of
VCC.
