Procurement Notes

Verify the specific suffix (EL) against the manufacturer's current datasheet to confirm packaging details and RoHS compliance status. Ensure the ordering part number matches the required tape and reel specifications for automated assembly processes. Cross-reference the latest revision history to confirm pinout compatibility with existing designs.

Selection Notes

Select this component when designing systems that require dual D-type flip-flops with low voltage operation and high speed. The 74LCX series offers improved switching speeds compared to standard 74HC logic while maintaining lower power consumption. Consider the TSSOP-16 package size for space-constrained PCB layouts and ensure supply voltage levels remain within the specified 1.65V to 3.6V range.

Part Context

This component belongs to the Toshiba 74LCX series, which represents low-voltage high-speed CMOS logic technology. The series is designed to replace higher voltage logic families in modern portable devices. The TC74LCX74 specifically provides dual D-type flip-flop functionality, making it a fundamental building block for sequential logic circuits in digital design.

Replacement Considerations

Direct substitutes include the TC74LCX74F and TC74LCX74FK. Verify pinout compatibility and electrical characteristics before substitution. Alternative manufacturers may offer equivalent parts such as the SN74LVC74A or MC74LCX74D, but input/output voltage levels must be confirmed.
