QS74FCT841ATP

Latches Overview

The QS74FCT841ATP is an octal buffer and line driver from the FCT logic series, manufactured by Quality Semiconductor. It features eight true outputs designed for high-speed digital signal transmission. The component utilizes CMOS technology and operates within a standard voltage range typical for the FCT family. It is housed in a 20-pin PDIP package with a 0.300-inch body width. The device provides common control functionality to manage data flow direction or enable/disable states across all channels simultaneously.

Latches Feature Summary

• Octal configuration providing eight independent buffered output channels
• CMOS construction ensuring low power consumption and high noise immunity
• Common control mechanism for unified direction or tri-state management
• True output polarity maintaining input signal integrity without inversion

Latches Applications

• High-speed bus interface buffering in computer systems
• Signal driving for memory modules and peripheral connections
• Data line isolation in industrial control networks
• Clock distribution and synchronization circuits

Latches Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm package dimensions match design requirements. Check manufacturer datasheets for electrical characteristics. Ensure supply chain authenticity through authorized distributors. Review lead times due to potential discontinuation risks associated with older FCT series components.

Latches Selection Notes

Select this component when eight-channel buffering is required with FCT speed performance. Compare against similar octal buffers like the 74FCT541 if directionality is not needed. Consider pin compatibility with existing PCB layouts using DIP-20 footprints. Evaluate power supply constraints against standard FCT operating voltages. Assess thermal requirements based on load capacitance specifications.

Latches Part Context

This part belongs to the FCT (Fast CMOS) logic family, known for TTL-compatible speeds with CMOS power efficiency. Quality Semiconductor produced variants of IDT designs under license. The QS prefix denotes specific manufacturing origin. Similar parts include the IDT74FCT841 and other octal transceivers in the same logical category.

Latches Replacement Considerations

The IDT74FCT841ATP is a direct functional equivalent from Integrated Device Technology. Verify pinout compatibility before substitution. Check voltage levels and output drive strengths against original specifications. Ensure package type matches the existing socket or footprint.
