Procurement Notes

Verify the specific ordering suffix 'DT' corresponds to the tape-and-reel packaging format as defined in the official datasheet. Confirm that the device meets the required RoHS compliance standards for your region. Ensure that the operating temperature range specified aligns with your application's environmental conditions. Cross-reference the part number with the manufacturer's latest documentation to confirm availability and any potential obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when an octal buffer with 3-state control is needed for low-voltage logic levels. Consider its overvoltage tolerance if interfacing with higher voltage domains. Evaluate the package type options available for your PCB layout constraints. Compare power consumption requirements against other series members to ensure optimal efficiency for your specific design needs.

Part Context

This part belongs to the LCX family of low-voltage CMOS logic devices from onsemi. The LCX series is characterized by its ability to operate at voltages down to 1.65V while maintaining high speed performance. It serves as a successor to older LVC and LVX families, offering improved noise immunity and lower power dissipation. The MC74LCX652 specifically addresses the need for wide data bus buffering in modern digital systems.

Replacement Considerations

Check for direct pin-compatible alternatives such as the MC74LCX652M or other variants within the same LCX family that may offer different packaging options. Verify functional equivalence regarding voltage ranges and drive strengths before substituting. Consult the manufacturer's cross-reference guide for approved replacements to ensure compatibility.
