Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-20 package and 'G4' indicates RoHS compliance and green material status. Confirm the datasheet version matches the manufacturing date code. Ensure ESD handling procedures are followed during assembly due to CMOS sensitivity. Cross-reference the ordering part number with the manufacturer's current catalog to confirm availability and pinout consistency.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing between 3.3-V logic domains requiring high-speed data transfer. The LVT series offers faster switching speeds compared to standard LVC devices. Consider the TSSOP package for space-constrained surface-mount designs. Evaluate the 64 mA sink current for driving heavy capacitive loads on shared buses. Ensure supply voltage remains within the 2.7-V to 3.6-V window for optimal performance.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVT245B family of octal bus transceivers. It serves as a low-voltage successor to older 5-V bus interface standards. The device facilitates efficient data routing in embedded systems where multiple masters and slaves share a common data path.
