Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DGGR' against the manufacturer's current documentation to confirm the tape-and-reel packaging configuration. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the datasheet revision date to validate electrical characteristics before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 18-bit wide data paths at 5V logic levels. It serves as a suitable alternative to standard 16-bit transceivers where additional channel count is necessary without increasing pin count significantly. Consider its propagation delay specifications relative to system clock speeds.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments 74ABT family, which utilizes BiCMOS technology to achieve performance comparable to LSTTL while maintaining CMOS power consumption benefits. The ABTH variant typically includes internal pull-up resistors, whereas the standard ABT version may not, depending on the specific sub-series documentation.
