74HCT4040 - 12-stage binary ripple counter

Download the 74HCT4040 datasheet PDF. This datasheet also covers the 74HC4040 variant, as both devices belong to the same 12-stage binary ripple counter family and are provided as variant models within a single manufacturer datasheet.

General Description

The 74HC4040; 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.

Key Features

  • Wide supply voltage range from 2.0 V to 6.0 V.
  • CMOS low power dissipation.
  • High noise immunity.

74HC4040; 74HCT4040 12-stage binary ripple counter Rev. 8 — 16 February 2024 Product data sheet 1. General description The 74HC4040; 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. 2. Features and benefits • Wide supply voltage range from 2.0 V to 6.
