Product data sheet
1. General description
The 74HC4040-Q100; 74HCT4040-Q100 is a 12-stage binary ripple counter with a clock
input (CP), an overriding asynchronous master reset input (MR) and twelve parallel
outputs (Q0 to Q11). 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 that
enable 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.
