Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DBR' corresponds to the SOIC-20 package and tape-and-reel packaging configuration. Confirm that the component meets RoHS compliance requirements as indicated in manufacturer documentation. Ensure the procurement source provides valid traceability for the Texas Instruments manufacturing lot. Cross-reference the datasheet revision to confirm pinout and electrical characteristics match the design specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 3.3-V logic interface is required for high-speed data transmission. The 64 mA low-level sink capability makes it suitable for driving heavier loads compared to standard CMOS devices. Consider the 2.3 ns propagation delay for timing-sensitive applications. Ensure the system power supply remains within the 2.7 V to 3.6 V range to maintain signal integrity and proper logic level translation.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVT245B family of octal bus transceivers. It utilizes ABT technology to optimize speed and power consumption for 3.3-V systems. The device serves as a bridge between different logic domains, facilitating efficient data routing in digital circuits. It is distinct from the SN74LVC8T245, which supports a wider voltage range including 1.65 V.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74LVT245BDWR is a direct functional substitute with identical electrical characteristics. Verify package compatibility if transitioning between reel and tube formats. Other variants in the SN74LVT245B series may offer different packaging options but share the same core functionality.
