Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance as per manufacturer standards. Confirm the SOIC-8 package dimensions match your PCB footprint constraints. Ensure the operating temperature range of 0°C to +70°C aligns with your environmental specifications. Check that the 350 ns propagation delay meets your timing requirements. Validate the tape and reel packaging format against your automated assembly equipment.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when dual channel peripheral driving is required with high current and voltage capabilities. Consider the 350 ns propagation delay for timing-sensitive designs. The 8-SOIC package offers a compact solution for surface mount assembly. Verify compatibility with standard 5V logic families given the 4.5V to 5.5V operating range. Evaluate thermal dissipation needs against the 725 mW power rating.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN75476 through SN75478 family of dual peripheral drivers from Texas Instruments. These devices are specifically designed to handle high current and high voltage loads while maintaining fast switching performance. The SN75477 variant provides two independent output channels within a single integrated circuit, making it suitable for compact peripheral control applications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN75477DR serves as a tube-packaged alternative within the same functional family. SN75477DE4 is another lead-free variant available in tube packaging. SN75477D represents the standard non-leaded version in tube form. Verify pinout and electrical characteristics remain identical before substitution.
