SN74LV4040ADRG4

Counter Dividers Overview

The SN74LV4040ADRG4 is a 12-bit asynchronous binary counter from Texas Instruments, part of the LV-A logic series. It operates on a single power supply ranging from 2 V to 5.5 V and supports counting rates up to 95 MHz. The device features negative-edge triggering and an asynchronous reset function. It is housed in a TSSOP-16 surface-mount package and functions within a temperature range of -40°C to +85°C.

Counter Dividers Feature Summary

• Provides 12-bit asynchronous binary counting capability with negative-edge clock triggering.
• Includes an asynchronous reset input for immediate state initialization.
• Supports wide voltage operation from 2 V to 5.5 V for flexible system integration.

Counter Dividers Applications

• Digital frequency division circuits
• Event counting systems
• Timing sequence generation

Counter Dividers Procurement Notes

Verify the specific suffix 'DRG4' against official datasheets to confirm RoHS compliance and lead-free status. Ensure the TSSOP-16 package dimensions match the target PCB footprint. Confirm that the operating voltage requirements align with the system's power supply rails before finalizing procurement.

Counter Dividers Selection Notes

Select this component when a 12-bit asynchronous counter is required within the LV-A logic family. It is suitable for applications needing high-speed counting up to 95 MHz. Consider the TSSOP-16 package if space constraints favor surface-mount technology over through-hole alternatives like the DIP variant.

Counter Dividers Part Context

This part belongs to the SN74LV4040A family of 12-bit asynchronous binary counters. It shares functional similarities with other members like the SN74LV4040APWR but differs in packaging and manufacturing revisions indicated by the suffix. It is designed for general-purpose digital logic applications requiring reliable binary counting.

Counter Dividers Replacement Considerations

SN74LV4040APWR offers identical functionality in a TSSOP-16 package. SN74LV4040AN provides the same logic in a 16-PDIP through-hole package. Verify pin compatibility and thermal characteristics when substituting.
