Counter Dividers Procurement Notes

Verify the specific manufacturer source, as this component has been associated with both Fairchild Semiconductor and onsemi due to corporate acquisition history. Confirm that the datasheet corresponds to the exact part number suffix to ensure compatibility with required pinout and electrical specifications before integration into designs.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit binary counter is required within the ACT logic family. Ensure the design environment supports the specified 4.5V to 5.5V operating voltage range. Consider the SOIC-16 package constraints for PCB layout and thermal management requirements relative to the application's power dissipation limits.

Counter Dividers Part Context

This component is part of the broader 74ACT logic family, which provides high-speed performance comparable to TTL but with CMOS power efficiency. The 74ACT163 variant specifically offers synchronous preset and clear functions, distinguishing it from asynchronous counterparts. It serves as a fundamental building block for complex digital counters and timers in industrial and consumer electronics.

Counter Dividers Replacement Considerations

The 74ACT163MTCX is documented as a functional equivalent offering identical binary counting capabilities in a TSSOP-16 package. Verify pin-to-pin compatibility and electrical parameter alignment when substituting between these package variants.
