SN74HC4040NSR

Counter Dividers Overview

The SN74HC4040NSR is a 12-stage asynchronous binary counter from the Texas Instruments 74HC series. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range of -40°C to 85°C. The device features a maximum clock frequency of 33 MHz at 6 V and typical propagation delays of 12 ns. It utilizes negative-edge triggering for counting and includes an asynchronous clear input that resets all outputs to a low state upon receiving a high signal.

Counter Dividers Feature Summary

• Provides 12 external output stages for full binary count visibility
• Features asynchronous clearing capability via dedicated control input
• Supports operation across a wide voltage range suitable for various logic families

Counter Dividers Applications

• Time-delay circuits
• Counter controls
• Frequency-dividing circuits

Counter Dividers Procurement Notes

Verify the specific package type and reel quantity against project requirements, as the 'SR' suffix indicates tape-and-reel packaging. Confirm RoHS compliance status and lead finish specifications with the manufacturer or authorized distributor prior to ordering. Ensure the selected variant matches the required thermal and electrical performance parameters for the intended application environment.

Counter Dividers Selection Notes

Select this component when a 12-bit asynchronous binary counter is required with external access to all stage outputs. Consider the HC logic family for compatibility with standard CMOS interfaces and moderate speed applications. Evaluate the 16-pin SOP package constraints regarding board space and thermal dissipation relative to other available package options in the SN74HC4040 family.

Counter Dividers Part Context

This device belongs to the SNx4HC4040 family of 12-bit asynchronous binary counters manufactured by Texas Instruments. The family encompasses multiple package variations including SOIC, PDIP, TSSOP, and SSOP. The SN74HC4040NSR specifically denotes the surface-mount SOP variant supplied in a tape-and-reel format for automated assembly processes.

Counter Dividers Replacement Considerations

Direct replacements include SN74HC4040DR and SN74HC4040PWR. Verify pinout compatibility and package dimensions before substituting.
