Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DLR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the 48-SSOP footprint matches the target PCB design constraints. Ensure the selected component meets the necessary RoHS compliance standards for the intended manufacturing environment. Cross-reference the datasheet revision to validate the exact propagation delay specifications against system timing requirements.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-channel buffer with three-state control is required for parallel data lines. The AHC series offers a balance of speed and power consumption suitable for general-purpose digital systems. Consider the 2 V to 5.5 V operating range for compatibility with various logic families. The SSOP-48 package is appropriate for space-constrained designs requiring surface mount technology.
