Procurement Notes

Verify the exact suffix 'TR3' indicates tape and reel packaging when sourcing. Confirm the manufacturer origin as Fairchild Semiconductor or its successors, such as ON Semiconductor, due to corporate acquisitions. Ensure the component meets RoHS compliance standards if required for your specific application. Cross-reference datasheets for any pinout variations between different manufacturing batches.

Selection Notes

Select this component when a compact, low-power quad NAND gate is required for digital logic applications. Consider the 2V to 6V operating range for compatibility with both 3.3V and 5V systems. Evaluate the SOIC package size against available PCB real estate. Ensure the speed characteristics meet the timing requirements of your specific circuit design.
