Part Number : 74HCT4040N
Function : 12-stage Binary Ripple Counter
Package : DIP, SO, SSOP 16 Pin Type
Maker : Philips Electronics
The 74HC4040, 74HCT4040N, 74HCT4040 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.
