Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the exact suffix 'SJ' against official onsemi documentation, as standard commercial variants typically use 'SCX' or 'MTCX'. Confirm package dimensions and marking specifications directly from the manufacturer's datasheet to ensure mechanical compatibility. Check for RoHS compliance status and moisture sensitivity level requirements specific to this suffix variant before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select the 74ACT244SJ when designing systems requiring octal buffering with three-state control and TTL input compatibility. Ensure the application voltage falls within the 2V to 6V range to maintain specified electrical characteristics. Consider the TSSOP package constraints for thermal management and PCB layout. Verify that the required propagation delay and drive current meet the system's timing and load demands.

Buffers, Drivers, Receivers, Transceivers Part Context

The 74ACT244 series represents a high-performance CMOS logic family offering speed comparable to LS-TTL with lower power consumption. This specific component functions as an octal buffer, distinct from transceivers like the 74ACT245 which include direction control. It is part of onsemi's standard product portfolio aimed at improving circuit density and signal integrity in digital systems.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Cross-reference with MC74AC244 for AC logic equivalents or MC74HCT244 for HCT logic variants. Verify pinout compatibility and electrical parameter alignment, particularly output drive strength and input threshold levels, before substituting.
