Latches Procurement Notes

Verify the specific suffix 'SJ' corresponds to the intended tape-and-reel packaging format and temperature grade. Confirm that the manufacturer designation aligns with current Fairchild or ON Semiconductor product lines due to corporate acquisitions. Ensure compliance with RoHS directives if required by your manufacturing standards. Cross-reference the datasheet revision date to confirm pinout and electrical specifications have not changed in recent updates.

Latches Selection Notes

Select this component when an octal latch with three-state capability is required for low-voltage digital interfaces. It is suitable for designs transitioning from older 5V or 3.3V LVC/LCX families where space and power are constrained. Consider the operating voltage range and output drive strength relative to load requirements. Ensure the package type matches the PCB footprint constraints and thermal management needs of the final assembly.

Latches Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic devices, known for their compatibility with 3.3V systems while offering improved performance over earlier generations. The 74LCX373 specifically addresses the need for octal latches in high-density applications. As part of the broader 74-series logic family, it maintains standard pinouts for ease of migration from previous design iterations.

Latches Replacement Considerations

Check for equivalents such as the 74LVC373 or 74HC373 depending on voltage tolerance. Verify pin compatibility before substituting with other manufacturers' octal latches. Ensure the replacement supports the same supply voltage range and output drive characteristics.
