DESCRIPTION
The 74LV4040 is a low–voltage Si–gate CMOS device and is pin
and function compatible with 74HC/HCT4040.
The 74LV4040 is a 12-stage binary ripple counter with a click input
(CP), an overriding asynchronous master reset input (MR) and
twelve fully buffered parallel outputs (Q
advanced 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.
