Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer designation as NXP USA Inc. or Philips Semiconductors depending on the production era. Confirm the SSOP-20 package type (SOT339-1) matches the DB suffix. Ensure the ordering code includes the ,118 suffix for standard reel packaging. Check for RoHS compliance status if required for specific manufacturing environments.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring octal buffering with inversion and high-speed performance. The ABT logic family offers superior speed compared to standard HCT or LVC families. Consider the 3-State capability for bus sharing applications. Verify that the 5V supply requirement aligns with the system voltage rails.
