MC74AC574DTR2

Flip Flops Overview

The MC74AC574DTR2 is an obsolete octal D-type flip-flop manufactured by onsemi, housed in a 20-TSSOP surface-mount package. It features positive-edge triggering and three-state non-inverting outputs. The device operates within a supply voltage range of 2V to 6V, with a maximum propagation delay of 9.5ns at 5V and 50pF load. It supports a clock frequency up to 95 MHz, draws 8 µA static current, and provides 24mA output drive capability. The component functions across an operating temperature range of -40°C to 85°C.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with positive-edge clock triggering for synchronous data storage.
• Three-state non-inverting outputs enabling direct interface with bus-oriented systems via high-impedance states.
• CMOS construction supporting wide supply voltage operation from 2V to 6V with low static power consumption.

Flip Flops Applications

• Bus-oriented system data latching and buffering
• High-speed digital signal processing synchronization
• Parallel-to-serial data conversion interfaces

Flip Flops Procurement Notes

This specific part number is officially obsolete and no longer manufactured by onsemi. Verification of availability should focus exclusively on the listed substitute components. Ensure that replacement parts match the original pinout and electrical specifications. Confirm RoHS compliance status differences between the legacy unit and active substitutes before integration into new designs.

Flip Flops Selection Notes

Designers requiring this logic family should evaluate the active MC74AC574DTR2G variant or alternative packages such as the SOIC version (MC74AC574DWR2). Considerations must include package dimension compatibility, thermal performance under load, and verification of updated environmental compliance standards compared to the discontinued model.

Flip Flops Part Context

The MC74AC574DTR2 belongs to the 74AC series of high-speed CMOS logic devices produced by onsemi. This series is characterized by fast propagation delays and wide operating voltage ranges, distinguishing it from standard HC or LS logic families. The device serves as a fundamental building block for sequential logic circuits requiring reliable data retention and high-frequency operation capabilities.
