74AHC574D,118

Overview

The Nexperia 74AHC574D,118 is an octal D-type flip-flop with 3-state outputs manufactured by Nexperia USA Inc. It operates within a supply voltage range of 2V to 5.5V and features a maximum propagation delay of 10.6ns at 5V with 50pF load. The device supports a clock frequency up to 115 MHz, provides output drive currents of 8mA for both high and low states, and maintains a static current of 4 µA. Packaged in a 20-SOIC (7.50mm wide) surface-mount format, it functions as a positive-edge triggered element suitable for bus-oriented applications.

Feature Summary

• Octal D-type flip-flop architecture with positive-edge triggering mechanism
• Three-state non-inverting outputs enabling efficient bus-oriented system integration
• Wide operating temperature specification supporting industrial environmental conditions

Applications

• Bus-oriented data storage and transfer systems
• Microprocessor input or output port interfacing
• Parallel-to-serial data conversion circuits

Procurement Notes

Verify the specific ordering suffix matches the required package configuration before procurement. Confirm that the component meets RoHS3 compliance standards for your manufacturing process. Ensure the supplier source aligns with authorized Nexperia distribution channels to guarantee authenticity. Cross-reference the datasheet revision against your design requirements to avoid potential pinout or electrical characteristic discrepancies during production integration.

Selection Notes

Select this component when an octal storage solution with three-state capability is required for high-speed digital logic applications. The AHC series offers superior speed compared to standard HC logic while maintaining CMOS power efficiency. Consider the 20-SOIC package dimensions for PCB layout constraints. Verify that the 5.5V maximum supply rating aligns with the target system voltage levels to ensure reliable operation without exceeding absolute maximum ratings.

Part Context

This part belongs to the 74AHC family of high-speed CMOS logic devices produced by Nexperia. The 74AHC574 serves as the base part number for the octal D-type flip-flop configuration. The ',118' suffix indicates the specific tape and reel packaging format used for automated assembly processes. This family is designed to replace older 74LS logic families with improved performance characteristics and lower power consumption profiles.

Replacement Considerations

The 74AHCT574D,118 is a compatible alternative offering TTL-compatible input levels instead of CMOS levels.
