• Three-state non-inverting outputs allowing direct bus line connections
• High-speed CMOS technology enabling operation up to 115 MHz
• Wide operating voltage range supporting 2 V to 5.5 V power supplies

Applications

• Parallel-to-serial and serial-to-parallel data conversion interfaces
• Register banks for temporary data storage in microprocessor systems
• Buffering and driving of external loads via three-state outputs
• Timing synchronization and pulse generation circuits

Procurement Notes

Verify the complete part number including the suffix ,118 to ensure correct packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for any recent Product Change Notifications regarding assembly or labeling updates. Ensure ESD handling procedures are followed during installation due to CMOS sensitivity.

Selection Notes

Select this component when eight synchronized D-type registers are required in a compact surface-mount form factor. The wide voltage range accommodates both 3.3 V and 5 V logic systems. Consider the TSSOP-20 package dimensions against available PCB space. Verify that the 115 MHz speed rating meets the system clock requirements and that the ±8 mA drive strength is sufficient for the connected load capacitance.

Part Context

This component belongs to the Nexperia 74AHC series, which offers high-speed CMOS performance comparable to standard TTL logic but with lower power consumption. The AHC family is designed for modern low-voltage digital applications requiring fast switching speeds and wide operating voltage flexibility. It serves as a fundamental building block for sequential logic design in consumer electronics and industrial control systems.

Replacement Considerations

Cross-reference with other manufacturers' 74AHC574 equivalents such as SN74AHC574PWR from Texas Instruments or MC74AHC574ADTR2G from ON Semiconductor. Ensure pinout compatibility and verify that electrical parameters like propagation delay and output current meet or exceed original specifications.
