Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the G4 suffix to ensure compliance with specific environmental directives such as RoHS3. Confirm the package type matches the design footprint requirements. Check the datasheet revision history for any updates to electrical characteristics or recommended operating conditions before finalizing the bill of materials.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering with tri-state control on a standard 5V supply. Ensure the application falls within the specified commercial temperature range. Consider the 74LS series propagation delays and power consumption relative to other logic families if higher speed or lower power is required.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is a specific variant of the SN74LS244 octal buffer, distinguished by its tape-and-reel packaging indicated by the 'R' suffix and lead-free/RoHS compliance indicated by 'G4'.
