Product data sheet
1. General description
The 74HC4020-Q100; 74HCT4020-Q100 are 14-stage binary ripple counters 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.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.
