• 74HC4040 IC - 12-Stage Binary Ripple Counter IC (744040 IC)


74HC4040 is a 16 Pin 12-Stage Binary Ripple Counter IC having 2V to 6V Operating Voltage range with 1uA low input current. It has 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.
