Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix RE4 indicates RoHS compliance and green material status as per Texas Instruments documentation. Confirm the SOIC-20 package type matches your PCB footprint requirements. Ensure the 4.5V to 5.5V operating voltage aligns with your system power rails. Check that the 64mA/32mA drive currents meet your load specifications. Validate the -40°C to +85°C industrial temperature rating against your environmental constraints.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed, high-drive octal bus interfacing is required at 5V logic levels. The BCT technology offers faster switching than standard LS series while maintaining CMOS compatibility. Consider the 4.5ns propagation delay for timing-sensitive designs. Evaluate the 20-pin SOIC package for surface-mount assembly needs. Compare against ABT or ACT families if different speed or voltage characteristics are needed.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74BCT2245 family of octal bus transceivers from Texas Instruments. It is designed for use in systems requiring bidirectional data transfer between buses. The device integrates direction control and output enable functions typical of the 2245 architecture. It serves as a bridge between microprocessors and peripheral devices or memory modules.
