Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status via current material declarations. Check for obsolescence notices as the lifecycle status indicates discontinuation. Ensure packaging specifications match design requirements before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring octal buffering with three-state control. Verify that the SOP-20 package fits the PCB layout constraints. Ensure the 4.5 V to 5.5 V supply voltage aligns with the system power rails. Consider the 8.5 ns propagation delay against timing requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ACT240 series of octal buffers and line drivers. It shares functional characteristics with other variants like the 74ACT240MTC but differs in package type. The SOP-20 form factor distinguishes it from TSSOP or SOIC alternatives within the same logic family.
