Flip Flops Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific ordering suffixes that may indicate tape-and-reel packaging variations. Ensure the part number matches the exact 20-TSSOP specification required for your PCB footprint. Review datasheet revisions for any updates to electrical characteristics or recommended operating conditions prior to final procurement.

Flip Flops Selection Notes

Select this component when designing systems requiring octal data latching with high-speed performance and TTL compatibility. The ACT series offers superior speed compared to HC variants while maintaining CMOS power efficiency. Consider the 24mA output drive strength for driving moderate loads directly. Evaluate the 160 MHz maximum clock frequency against system timing requirements. Ensure the 20-TSSOP package dimensions align with available board space and assembly capabilities.

Flip Flops Part Context

This device is part of the broader 74ACT family of advanced CMOS logic integrated circuits. It serves as a functional equivalent to bipolar Schottky TTL devices but utilizes modern silicon gate CMOS technology. The 74ACT series is widely used in applications demanding fast switching speeds and reliable operation across industrial temperature ranges. It complements other members of the family such as latches and buffers within complex digital logic designs.

Flip Flops Replacement Considerations

Public confirmed substitutes include MC74ACT374DTR2G from onsemi and SN74ACT574DBR from Texas Instruments. Verify pinout compatibility and electrical parameter alignment before substitution. Note that the MC74ACT374DTR2G is listed as a direct replacement, while the SN74ACT574DBR is categorized as similar. Check package type differences between TSSOP and SOIC if applicable.
