Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix G4 indicates lead-free composition and RoHS compliance during procurement. Confirm the SOIC-20 package dimensions match your PCB footprint requirements. Ensure the standard industrial temperature range meets your environmental specifications. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed switching is required alongside significant low-state drive capability. The 74F series offers faster performance than standard 74LS equivalents. Consider the three-state feature if multiple devices share a common data bus. Verify that the 4.5V to 5.5V supply voltage aligns with your system power rails.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is part of the broader 74F family of high-speed CMOS logic devices. It shares the same pinout and logical function as the SN74F244DW but includes the G4 suffix denoting specific manufacturing attributes regarding material composition. It serves as a direct replacement for other octal buffers in legacy designs requiring F-series speed characteristics.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74F244DW is the primary equivalent without the lead-free suffix. Other compatible parts include the SN74AS240ADW and SN74BCT240DW, though these may differ in inversion polarity or drive strength.
