SN74HC4040DRG4

Overview

The SN74HC4040DRG4 is a 12-bit asynchronous binary counter from the Texas Instruments HC logic family. 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 high-level clear input that asynchronously resets all outputs low and advances the count on a high-to-low clock transition. It provides external access to all stage outputs and includes low power consumption characteristics with a maximum ICC of 80 µA.

Feature Summary

• Provides 12-stage asynchronous binary counting capability with all outputs available externally
• Features asynchronous clearing via a high-level signal at the clear input to reset all outputs low
• Operates across a wide supply voltage range of 2 V to 6 V for flexible system integration
• Designed for low power consumption with minimal supply current requirements

Applications

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

Procurement Notes

Verify the specific ordering suffix 'G4' against the manufacturer's latest documentation to confirm lead-free status and RoHS compliance details. Ensure the SOIC-16 package dimensions match the target PCB footprint requirements. Confirm the active production status directly with Texas Instruments, as component availability and manufacturing statuses are subject to change without notice.

Selection Notes

Select this component when a 12-bit asynchronous binary counter is required for digital timing or frequency division tasks. The HC logic family ensures compatibility with standard CMOS interfaces while maintaining low power dissipation. Verify that the operating voltage range of 2 V to 6 V aligns with the system power supply constraints and that the -40°C to +85°C industrial temperature rating meets environmental specifications.

Part Context

This part belongs to the SNx4HC4040 series of 12-bit asynchronous binary counters manufactured by Texas Instruments. The 'G4' suffix indicates a lead-free and RoHS-compliant version of the standard SN74HC4040 device. It is part of the broader 74HC logic family, designed for general-purpose digital applications requiring reliable binary counting functions in commercial and industrial environments.

Replacement Considerations

Direct replacements include SN74HC4040DR and SN74HC4040DBR. Other compatible variants within the same family may be considered if pinout and electrical specifications remain identical.
