74LVC245ABX-Q100X

Overview

The Nexperia 74LVC245ABX-Q100X is an octal bus transceiver with 3-state outputs, qualified to AEC-Q100 Grade 1 for automotive use. It operates on a supply voltage range of 1.2 V to 3.6 V and features 5.5 V tolerant inputs/outputs. The device includes Schmitt-trigger action at all inputs and IOFF circuitry for partial power-down applications. It supports mixed 3.3 V and 5 V environments and complies with JEDEC standards JESD8-7A, JESD8-5A, and JESD8-C/JESD36.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 (Grade 1)
• IOFF circuitry provides partial power-down mode operation
• Schmitt-trigger action at all inputs for tolerance of slower input rise and fall times
• DHVQFN package with Side-Wettable Flanks enabling Automatic Optical Inspection (AOI) of solder joints

Applications

• Automotive applications
• Mixed 3.3 V and 5 V environments
• Partial power-down applications

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.

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.

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.

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.
