Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix DTR2 to confirm the tape-and-reel packaging configuration and quantity per reel. Ensure the component matches the active or obsolete status indicated by the manufacturer, as availability may vary. Cross-reference the full part number against official onsemi databases to validate RoHS compliance and lead time requirements before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing low-voltage digital circuits requiring buffered signals with high drive strength. It is suitable for applications needing 5 V tolerance on inputs while operating from lower supply rails. Consider the TSSOP-14 package for space-constrained PCB layouts. Evaluate propagation delay specifications against system timing requirements to ensure signal integrity across the four channels.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the 74LCX series of low-voltage CMOS logic devices. It functions as a buffer and line driver, distinct from inverters or transceivers. The LCX series is characterized by its ability to operate at reduced voltages compared to standard 5 V logic families, making it ideal for modern portable and battery-powered electronic designs requiring efficient power management.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74LCX125MTC is identified as a direct substitute for the MC74LCX125DTR2. Verify pinout compatibility and electrical specifications before implementation. Note that the MC74LCX125DTR2 may be listed as obsolete by the manufacturer.
