Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the presence of the 'E4' suffix or specific manufacturer markings to confirm the RoHS-compliant variant. Ensure the SOIC-20 package dimensions match the design footprint. Confirm that the operating temperature range meets system requirements before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed performance is not critical but cost-effectiveness and robustness are priorities. It serves as a suitable replacement for older LS-series designs requiring octal buffering. Consider alternative ACT or HCT series variants if faster propagation delays or lower power consumption are required for the specific application.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments 74LS logic family, known for its widespread adoption in legacy digital systems. The SN74LS244 specifically addresses the need for octal buffering with tri-state capability. It is distinct from the SN74LS240, which provides inverted outputs. The DWG4 designation indicates the specific tape-and-reel or tube packaging configuration associated with the green/RoHS-compliant version.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LS244DWR is a direct pin-to-pin replacement offering identical electrical characteristics and functionality within the same logic family.
