Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DB' corresponds to the SSOP-20 package configuration required for your PCB layout. Confirm the device status as active or obsolete through official Texas Instruments channels prior to finalizing design-in decisions. Ensure compatibility with existing 5V logic levels and check for any recent product change notifications affecting pinout or electrical characteristics.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed signal buffering is required in 5V systems using standard TTL-compatible logic families. The tri-state capability makes it suitable for bidirectional data buses where multiple devices share common lines. Consider the SSOP package constraints regarding thermal dissipation and board space compared to larger DIP alternatives.
