Counter Dividers Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the part matches the specific SN74LS161AD designation and packaging details. Review the latest datasheet revisions to ensure compatibility with current design specifications. Check for any obsolescence notices or lifecycle changes before finalizing procurement plans.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit binary counter with edge-triggered functionality is required. Ensure the design accommodates the specified 4.75 V to 5.25 V supply voltage range. Consider the 16-pin SOIC package dimensions for PCB layout constraints. Verify that the 0°C to 70°C operating temperature range meets the environmental requirements of the target application.

Counter Dividers Part Context

This component belongs to the broader family of synchronous 4-bit counters, which also includes variants like the SN74LS163. While sharing core counting logic, differences exist in reset mechanisms; the SN74LS161 typically utilizes asynchronous reset compared to the synchronous reset found in other family members. This distinction impacts timing behavior in digital designs requiring specific initialization sequences.
