Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'SJX' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging configuration and quantity. Ensure the component meets RoHS compliance requirements as stated in the latest documentation. Cross-reference the ordering part number with the distributor's catalog to confirm availability status, as lifecycle changes may affect procurement options.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring eight-bit wide bidirectional data paths operating at low voltages. The LCX series offers improved switching speeds compared to older CMOS families while maintaining compatibility with 5 V tolerant I/Os. Consider the 20-SOP package constraints for PCB layout and thermal management during the design phase.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74LCX125/245 family of low-voltage CMOS logic ICs manufactured by onsemi. The LCX series is engineered for high-speed performance with low static power consumption. The 2245 variant specifically provides octal bidirectional functionality, distinguishing it from unidirectional buffers or single-direction transceivers within the same logical family.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for equivalent parts such as the MC74LCX245 series from onsemi or compatible devices from other manufacturers like NXP or Texas Instruments. Verify pinout compatibility and electrical parameter alignment before substitution.
