Counter Dividers Procurement Notes

Verify the manufacturer designation on the datasheet, as Quality Semiconductor assets are often managed by Rochester Electronics or IDT. Confirm the specific suffix 'CTSO' matches the required package type and temperature rating. Ensure the source provides an official datasheet to validate electrical characteristics against current specifications.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit counter with parallel load is required. It is suitable for designs needing high-speed performance up to 100MHz. Consider the FCT logic family for compatibility with standard TTL/CMOS levels. Verify that the asynchronous reset and synchronous load functions align with the system control requirements.

Counter Dividers Part Context

This part belongs to the 74FCT logic family, which combines CMOS low power consumption with TTL-compatible drive strengths. The 74FCT163 variant specifically provides a 4-bit synchronous counter. Quality Semiconductor was a key producer before its acquisition, with documentation now often associated with Rochester Electronics or Integrated Device Technology.

Counter Dividers Replacement Considerations

Official substitutes include CD74FCT163, MC74FCT163, and SN74FCT163. These parts share identical logical functionality and pinouts. Verify package compatibility and operating temperature ranges before substitution.
