NLV74HC4040ADR2G

Counter Dividers Overview

The NLV74HC4040ADR2G is a 12-stage binary ripple counter manufactured by onsemi in the HC logic family. It consists of 12 master-slave flip-flops where each output frequency is half that of the preceding stage, advancing on the negative-going edge of the clock input. The device features an asynchronous active-high reset and operates within a voltage range of 2.0 to 6.0 V. It provides high noise immunity and low input current characteristics typical of CMOS devices.

Counter Dividers Feature Summary

• Contains 12 master-slave flip-flops for binary counting
• Features asynchronous active-high reset functionality
• Outputs divide clock frequency by powers of two
• Compatible with standard CMOS and LSTTL outputs

Counter Dividers Applications

• Time-base generators
• Frequency division circuits
• Binary counting applications

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'ADR2G' corresponds to the SOIC-16 package and tape-and-reel shipping configuration. Confirm the 'NLV' prefix indicates compliance with unique site and control change requirements as defined in the manufacturer's ordering information section.

Counter Dividers Selection Notes

Select this component when a 12-stage binary counter is required with asynchronous reset capability. Ensure the application design accounts for internal ripple delays which may cause decoding spikes at decoded outputs. Verify that the operating voltage falls within the specified 2.0 V to 6.0 V range for proper functionality.

Counter Dividers Part Context

This part belongs to the MC74HC4040A series of high-performance silicon-gate CMOS counters. It shares identical pinout with the standard CMOS MC14040 but offers improved performance characteristics. The device is designed for general-purpose digital counting and timing applications requiring multiple frequency division stages.

Counter Dividers FAQ

How does the reset function operate?

The reset is asynchronous and active-high. Applying a high level to the Reset input forces all Q outputs low immediately.

What causes decoding spikes in this device?

State changes of the Q outputs do not occur simultaneously due to internal ripple delays between the cascaded flip-flops.
