Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-20 package and tape-and-reel orientation. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact electrical specifications required for your design, as variations may exist within the same base model number.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with tri-state capability is needed for system buses. Consider the 2V to 5.5V operating range for compatibility with both 3.3V and 5V logic systems. Evaluate the TSSOP-20 package size against available PCB real estate. Compare propagation delay and drive current specifications against other AHC series alternatives if performance constraints are critical.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74AHC series of high-speed CMOS logic devices.
