Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant against the ordering information table, as the base part number covers multiple packages including SO20, TSSOP20, and DHVQFN20. Confirm that the suffix corresponds to the required temperature range and packaging format. Ensure compatibility with the target application's voltage levels and interface requirements before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an 8-bit bidirectional bus transceiver with 3-state outputs is required for automotive or industrial designs. It is suitable for interfacing between different logic families due to its wide supply voltage range and overvoltage tolerant inputs. Consider the DHVQFN package if space-saving and AOI inspection capabilities are necessary for the PCB layout.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74LVC/LVCH245A-Q100 family of octal bus transceivers. It shares functional similarities with other 74-series transceivers but is specifically optimized for low-voltage CMOS applications. The Q100 suffix indicates automotive qualification, distinguishing it from standard commercial variants while maintaining compatibility with common logic interfaces.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check the ordering information table for alternative package options within the same family, such as 74LVC245AD-Q100 or 74LVC245APW-Q100, which offer different physical footprints but identical electrical characteristics.
