MC74LCX574M

Flip Flops Overview

The MC74LCX574M is a low-voltage CMOS octal D-type flip-flop manufactured by onsemi. It operates within a supply voltage range of 2.3 V to 3.6 V and features five-volt tolerant inputs and outputs, enabling safe interfacing with 5.0 V devices. The device provides balanced 24 mA source and sink output drive capabilities. It includes an IOFF specification to guarantee high-impedance states when the supply voltage is zero, supporting live insertion applications. The component is housed in a 20-SSOP package.

Flip Flops Feature Summary

• Five-volt tolerant input and output interface capability for mixed-voltage systems
• IOFF specification ensures high-impedance state during power-off conditions
• Balanced 24 mA output drive strength for improved switching performance

Flip Flops Applications

• Interface between low-voltage logic and 5 V TTL circuits
• Live insertion and withdrawal system designs
• Octal data storage and buffering in portable electronics

Flip Flops Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and automotive qualification status. Confirm RoHS compliance and material composition requirements for your target market. Check current manufacturing status as legacy variants may be discontinued. Ensure ESD handling procedures are followed during assembly due to CMOS sensitivity.

Flip Flops Selection Notes

Select this component when a wide operating voltage range from 2.3 V to 3.6 V is required alongside 5 V compatibility. The 24 mA drive strength suits moderate load applications. Consider the 20-SSOP package for surface-mount constraints. Verify that the HC or ACT series alternatives do not better fit higher voltage or speed requirements if those parameters change.

Flip Flops Part Context

This part belongs to the 74LCX family of low-voltage CMOS logic devices. It serves as an octal register variant within the broader 74xx logic ecosystem. The LCX series is designed specifically for low-power applications requiring 5 V tolerance, distinguishing it from standard HC or LVC families which lack this specific interface feature.

Flip Flops Replacement Considerations

Direct substitutes include MC74LCX574DW and MC74LCX574DWR2G. Cross-manufacturer equivalents such as SN74LVC574ADBR or 74LVC574APW,118 may function similarly but require verification of voltage ranges and pinout compatibility.
