SN74LV4040ADBR

Counter Dividers Overview

The SN74LV4040ADBR is a 12-bit asynchronous binary counter from Texas Instruments, part of the LV-A logic series. It operates within a supply voltage range of 2 V to 5.5 V and supports an operating temperature range of -40°C to +85°C. The device is housed in a 16-pin SSOP package and features up-counting functionality with negative edge triggering.

Counter Dividers Feature Summary

• Provides 12-bit asynchronous binary counting capability
• Operates across a wide supply voltage range of 2 V to 5.5 V
• Designed for industrial temperature environments ranging from -40°C to +85°C

Counter Dividers Applications

• Digital frequency division circuits
• Timekeeping and clock generation systems
• Event counting applications in embedded devices

Counter Dividers Procurement Notes

Verify the specific ordering suffix 'DBR' corresponds to the 16-pin SSOP package with tape-and-reel delivery format. Confirm that the component meets RoHS compliance standards and matches the active production status indicated by Texas Instruments. Ensure compatibility with the required voltage levels and thermal conditions for the target application environment before finalizing procurement.

Counter Dividers Selection Notes

Select this component when a 12-bit asynchronous counter is required for low-voltage digital designs. The LV-A series offers compatibility with standard logic families while supporting operation down to 2 V. Consider the SSOP package constraints for PCB layout and ensure the negative edge trigger aligns with the system clock polarity requirements.

Counter Dividers Part Context

This part belongs to the SN74LV4040A family of 12-bit asynchronous binary counters manufactured by Texas Instruments. The family includes variants such as SN74LV4040APWR and SN74LV4040ADGVR, which differ primarily in packaging and reel specifications while maintaining identical logical functionality and electrical characteristics.

Counter Dividers Replacement Considerations

Direct substitutes include SN74LV4040APWR and SN74LV4040ADGVR. Verify pinout compatibility and package dimensions when swapping between SSOP and TSSOP formats.
