NXP 74HCT4040N 12-stage binary ripple counter DIL16

Manufactured by NXP - 74HCT4040N - DIL16 through hole package

Description

The 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.

Applications

• Frequency dividing circuits
• Time delay circuits
• Control counters
