Procurement Notes

Verify the specific ordering suffix (AE) against official Toshiba documentation to confirm exact packaging configuration and compliance status. Ensure the component matches the required 20-TSSOP footprint and pinout specifications for your design. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity. Check for any recent lifecycle notices or obsolescence warnings associated with this specific variant before finalizing procurement plans.

Selection Notes

Select this component when designing systems that require octal storage with tri-state control in low-voltage environments. It is suitable for applications needing high-speed data latching with minimal power consumption. Consider the 20-TSSOP package constraints for PCB layout. Compare against similar LCX series devices if different pin configurations or alternative voltage ranges are required for the specific application context.

Part Context

This component belongs to the 74LCX family of low-voltage CMOS logic integrated circuits manufactured by Toshiba Semiconductor and Storage. The 74LCX series is designed for high-speed operation while maintaining compatibility with standard 3.3V and 2.5V logic levels. The 74LCX374 specifically provides octal flip-flop functionality, distinguishing it from buffer or driver variants within the same logical family.

Replacement Considerations

Direct substitutes include the TC74LCX374FT and TC74LCX374FTELM from Toshiba. Other manufacturers offer equivalent parts such as the MC74LCX374 from ON Semiconductor and the 74LCX374AT20-13 from Diodes Incorporated. Verify pin compatibility and electrical parameters before substitution.
