QS74FCT193TQ

Counter Dividers Overview

The QS74FCT193TQ is a 4-bit bidirectional binary counter from the FCT series, manufactured by Quality Semiconductor. It operates on a 5 V supply with a range of 4.75 V to 5.25 V. The device features positive edge triggering and synchronous operation. It provides separate up and down clock inputs along with TCO (Terminal Count Output) for both directions. The component is housed in a PDIP-16 package and supports industrial temperature ranges.

Counter Dividers Feature Summary

• Synchronous 4-bit bidirectional counting capability
• Separate clock inputs for up and down operations
• Terminal count outputs for carry/borrow signaling

Counter Dividers Applications

• Digital frequency division circuits
• Timing control applications
• Binary counting systems

Counter Dividers Procurement Notes

Verify the specific suffix 'TQ' against official Quality Semiconductor documentation to confirm the exact package type and pinout configuration. Ensure that the operating voltage requirements align with your system design before integration. Confirm compliance status as datasheets may indicate non-qualified or unknown reach codes.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit counter with independent up/down control is required. The FCT series offers CMOS compatibility and standard logic levels. Consider the PDIP-16 package if through-hole mounting is necessary for your PCB layout constraints.

Counter Dividers Part Context

This part belongs to the FCT (Fast CMOS Technology) series, designed for high-speed digital applications. It serves as a fundamental building block for sequential logic circuits within larger digital systems, providing reliable binary counting functions.

Counter Dividers Replacement Considerations

Check for direct substitutes such as P74FCT193TSO from Pyramid Semiconductor. Verify pin compatibility and electrical specifications before substitution.
