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.
