Counter Dividers Procurement Notes

Verify the specific suffix 'SR' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Texas Instruments to ensure component authenticity. Check RoHS compliance status against current regulatory requirements. Validate the operating temperature range matches the intended environmental conditions. Ensure the 14-SOIC footprint aligns with the target PCB design constraints.

Counter Dividers Selection Notes

Select this component for designs requiring a simple, low-cost binary counter in a surface-mount format. It is suitable for general-purpose digital logic where moderate speed is sufficient. Consider the LS series power consumption characteristics relative to other logic families. Verify that the asynchronous clear feature meets the system reset requirements.
