QS74FCT161TQ

Counter Dividers Overview

The QS74FCT161TQ is a synchronous binary counter manufactured by Quality Semiconductor Inc. It operates in the up counting direction and utilizes CMOS technology. The device is housed in a PDSO16 package, which corresponds to an SSOP16 form factor with a .25-inch pitch. Key electrical parameters include a propagation delay of 5.6 ns at nominal supply voltage and a load capacitance of 50 pF. The maximum output current (Iol) is specified at 0.048 A. The component supports load/preset inputs and functions as a single binary counter unit.

Counter Dividers Feature Summary

• Synchronous operation with positive edge triggering for reliable data capture
• Up-counting direction capability for sequential binary value generation
• CMOS construction ensuring low power consumption and high noise immunity
• Integrated load and preset input functionality for flexible state control

Counter Dividers Applications

• Digital timing sequences requiring precise synchronization
• Address decoding logic in memory systems
• Event counting applications in embedded controllers
• Frequency division circuits within digital signal processing chains

Counter Dividers Procurement Notes

Verify RoHS compliance status prior to procurement, as documentation indicates non-compliance. Confirm package authenticity matches PDSO16/SSOP16 specifications. Ensure supplier provides valid traceability records for the Quality Semiconductor Inc origin. Check for moisture sensitivity level 1 handling requirements during storage and assembly processes to maintain device integrity.

Counter Dividers Selection Notes

Select this component when a synchronous 4-bit up counter is required in a compact surface-mount format. The 5.6 ns propagation delay suits moderate-speed digital designs. Verify that the 50 pF load capacitance aligns with downstream circuit requirements. Consider the 0.048 A drive capability for direct interfacing with standard CMOS loads without additional buffering stages.

Counter Dividers Part Context

This part belongs to the FCT series of logic components, designed for high-speed CMOS applications. Quality Semiconductor Inc produces this variant alongside other logical devices like decoders and bus drivers. The QS74FCT161TQ shares functional similarities with industry-standard binary counters but is distinguished by its specific packaging and manufacturer-defined electrical characteristics within the FCT family architecture.

Counter Dividers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with generic 74FCT161 equivalents only if electrical parameters such as propagation delay and Iol match exactly. Verify pin compatibility and package dimensions before substitution.
