Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for the SOIC-20 package. Confirm RoHS compliance status if required for your manufacturing process. Check for any recent product lifecycle notices or obsolescence warnings from the manufacturer before finalizing procurement plans.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when ten-channel buffering with three-state isolation is required. Compare propagation delay and drive strength against other ABT series variants like the SN74ABT244 or SN74ABT245. Consider the 5V operation requirement and ensure the system power supply aligns with the specified voltage range. Evaluate thermal performance for the chosen package style under expected load conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is part of the Texas Instruments SN74ABT family, which combines advanced BiCMOS technology with standard TTL-compatible inputs. The ABT series offers faster switching speeds than older LS or ALS families while maintaining similar pinouts for easy upgrades.
