Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'Q' indicates automotive or qualified grade requirements if applicable to your design. Confirm the 'DWR' suffix denotes the SOIC-20 package and reel packaging format. Ensure compatibility with your system's voltage levels and temperature specifications before finalizing procurement decisions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal transceiver with 3-state outputs is required for bidirectional data flow. Consider the 2 V to 5.5 V operating range for flexibility in various logic families. The 16.2 ns propagation delay suits general-purpose asynchronous communication needs rather than high-speed synchronous interfaces.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AHC series of advanced high-speed CMOS logic devices. It functions as an octal bus transceiver, distinct from flip-flops like the SN74AHC374 or other transceivers like the SN74HCT245. The 'Q' designation often implies specific qualification standards compared to standard commercial variants.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74AHC245DWR is a direct functional substitute without the 'Q' suffix. For TTL-compatible inputs, consider the SN74HCT245DWRE4. Higher speed options include the SN74ABTH25245DWR, though it requires a higher minimum supply voltage.
