MC74LVX574DWR2

Flip Flops Overview

The MC74LVX574DWR2 is an obsolete octal D-type flip-flop manufactured by onsemi. It features positive-edge triggering and three-state outputs within a single element containing eight bits. The device operates on a supply voltage ranging from 2V to 3.6V, with a maximum propagation delay of 18ns at 3.3V with 50pF load. Output drive capability is specified at 4mA for both high and low states, while quiescent current is 4µA. It utilizes a 20-SOIC package (0.295 inch width) and supports surface mount installation across a temperature range of -40°C to 85°C.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with positive-edge clock triggering
• Three-state non-inverting outputs for bus-oriented systems
• Low voltage CMOS technology compatible with 2V to 3.6V supplies

Flip Flops Applications

• Parallel data storage in digital communication interfaces
• Buffering and latching operations in microprocessor systems
• Data acquisition systems requiring multi-bit synchronization

Flip Flops Procurement Notes

This component is officially classified as obsolete and no longer manufactured by onsemi. Verification of availability requires checking authorized distributors for remaining stock or approved replacement parts. Direct procurement from the manufacturer is not possible. Ensure any sourced units are verified for authenticity and storage conditions prior to integration into designs.

Flip Flops Selection Notes

Designers should consider that this part is discontinued. Selection requires evaluating parameter equivalence with active substitutes such as the MC74LVX574DWR2G. Verify that alternative packages or slight pinout variations do not impact PCB layout. Confirm that voltage levels and output drive currents meet system requirements when transitioning to newer revisions or competitor equivalents.

Flip Flops Part Context

The MC74LVX574DWR2 belongs to the 74LVX series of low-voltage CMOS logic devices. This family provides performance comparable to standard TTL but operates at lower voltages. The specific model represents an octal configuration, offering eight independent D-type flip-flops in a single integrated circuit package, designed for high-density digital applications.

Flip Flops Replacement Considerations

MC74LVX574DWR2G is a confirmed direct substitute from onsemi.
