• Timing synchronization logic

Flip Flops Procurement Notes

Verify the manufacturer designation as Quality Semiconductor Inc when sourcing this component. Confirm the specific suffix 'TSOX' corresponds to the tape and reel packaging format if required for automated assembly processes. Ensure compatibility with the specified 5V supply voltage and check for any lead-free or RoHS compliance variations depending on the production batch date code.

Flip Flops Selection Notes

Select this component for designs requiring octal latching with high-speed performance up to 71.4 MHz. The 13 ns propagation delay makes it suitable for moderate-speed digital systems. Consider the PDSO20 package dimensions for PCB layout constraints. Verify that the input levels are compatible with the driving logic family, typically TTL or CMOS, as per the FCT series specifications.

Flip Flops Part Context

The QS74FCT377TSOX is part of the FCT (Fast CMOS) logic family produced by Quality Semiconductor Inc. This family bridges the speed of bipolar logic with the low power consumption of CMOS technology. The 377 variant specifically provides octal D-type flip-flops, distinguishing it from bus drivers like the 373 or multiplexers in the same series.

Flip Flops Replacement Considerations

Cross-reference models such as IDT74FCT377TSO-TR or CY74FCT377CTSOC may offer functional equivalence. Verify pinout compatibility and electrical characteristics before substitution. Note that manufacturers other than Quality Semiconductor Inc may have different suffix conventions for packaging or temperature grades.
