Procurement Notes
Verify the manufacturer part number 100393QCX against official Fairchild Semiconductor documentation to ensure authenticity. Confirm the package type is 28-PLCC (J-Lead) and check for any specific ordering suffixes that may affect pinout or electrical characteristics. Ensure the component status is active before procurement.
Selection Notes
Select this component when unidirectional translation from ECL to TTL is required in a compact form factor. The nine-channel architecture supports complex data buses. Verify voltage compatibility between the source ECL and destination TTL circuits. Consider the 28-PLCC package constraints for PCB layout and thermal management during system design.
Part Context
This component belongs to the Logic - Translators, Level Shifters category. It serves as a bridge between different logic families, specifically converting ECL signals to TTL levels. The device is manufactured by Fairchild Semiconductor and is identified by the DigiKey part number 2156-100393QCX-ND.
Replacement Considerations
Rochester Electronics LLC offers the 100393QCX as an alternative source. National Semiconductor Corporation also lists the 100393QC variant. Verify pin compatibility and electrical specifications before substituting.
