74HC4040D/AUJ

Counter Dividers Overview

The 74HC4040D/AUJ is a 12-stage binary ripple counter manufactured by Nexperia. It features 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, while a HIGH on MR clears all stages. It operates within a supply voltage range of 2.0 V to 6.0 V and supports temperatures from -40 °C to +125 °C. The device utilizes CMOS technology for low power dissipation and high noise immunity.

Counter Dividers Feature Summary

• Features an overriding asynchronous master reset input that forces all outputs LOW independent of the clock state.
• Includes input clamp diodes enabling interface to voltages exceeding VCC using current limiting resistors.
• Provides ESD protection exceeding 2000 V under Human Body Model testing.

Counter Dividers Applications

• Frequency dividing circuits
• Time delay circuits
• Control counters

Counter Dividers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature rating. Confirm the component status as active or obsolete before procurement planning. Ensure the selected variant matches the required logic family specifications for the target application environment.

Counter Dividers Selection Notes

Select this component for applications requiring a 12-bit asynchronous binary count sequence. Verify compatibility with the system's supply voltage range between 2.0 V and 6.0 V. Consider the negative edge-triggered clocking requirement and the availability of the SO16 package format for the design layout.

Counter Dividers Part Context

This component belongs to the 74HC series of high-speed CMOS logic devices produced by Nexperia. It functions as a digital counter utilizing silicon-gate CMOS technology. The device provides performance characteristics similar to LS-TTL logic while maintaining standard CMOS power consumption levels.

Counter Dividers Replacement Considerations

The 74HCT4040 serves as a functional alternative with TTL-compatible input levels. Other manufacturers produce equivalent parts such as the SN74HC4040DT. Verify pinout and electrical specifications when substituting.
