12-Stage Binary Ripple Counter IC – 74HC4040

The 74HC Series 74HC4040 IC is a 16 Pin 12-Stage Binary Ripple Counter IChaving 2V to 6V Operating Voltage range with a 1uA low input current. It has a clock input (CP),an overriding asynchronous master reset input (MR), and twelve parallel outputs (Q0 toQ11). The counter advances on the HIGH-to-LOW transition of CP.

A HIGH on MR clearsall counter stages and forces all outputs LOW, independent of the state of CP. Eachcounter stage is a static toggle flip-flop. Inputs include clamp diodes that enable the use ofcurrent limiting resistors to interface inputs to voltages in excess of VCC.
