Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'SCX' against the manufacturer's latest datasheet to confirm pinout compatibility and package dimensions. Ensure the procurement channel provides valid RoHS compliance documentation. Cross-reference the ordering information with official onsemi resources to avoid counterfeit components and ensure traceability.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require fast switching speeds and robust drive strength within standard 5 V logic environments. The ACT series offers superior performance compared to older AC or HC families. Consider the 20-pin SOIC package constraints and thermal management requirements for the intended application density.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ACT244 series of octal buffers. It serves as a critical interface component in digital electronics, bridging low-power logic sources with higher-capacitance loads. The ACT family combines CMOS low power consumption with TTL-compatible input levels and faster switching speeds than standard AC devices.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Compatible substitutes include the 74ACT244MTCX (TSSOP variant) and other 74ACT244 derivatives from onsemi. Verify pin-to-pin compatibility before substitution. Other manufacturers offering equivalent ACT logic buffers may also serve as alternatives if specifications align.
