Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-20 tape and reel packaging configuration. Confirm RoHS compliance status matches current manufacturing standards. Ensure the operating temperature range aligns with system thermal requirements. Check for any recent product change notices affecting marking or specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-supply 5V operation is required for an octal transceiver. Compare against LVC or AHC families if lower voltage support or different speed profiles are needed. Verify pin compatibility with existing PCB layouts designed for 20-pin surface mount packages. Consider power consumption differences compared to other logic families in the same footprint.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments 74ABT family, which utilizes Bipolar-CMOS-Logic technology. The '245' designation indicates an octal bus transceiver with direction control. The 'B' suffix typically denotes specific performance or package variations within the series. It serves as a standard interface solution for parallel data communication in digital systems.
