Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer origin as Fairchild Semiconductor or onsemi, noting corporate acquisitions. Confirm the package type matches the 20-Lead Small Outline Integrated Circuit (SOIC) standard JEDEC MS-013 specification. Ensure the ordering code suffix 'SC' corresponds to the correct physical dimensions and pinout configuration before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering with three-state control for bus isolation. Consider the specific propagation delay characteristics under varying load conditions and temperature ranges. Evaluate the power supply current requirements against system thermal constraints and ensure compatibility with the target logic family voltage levels.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74F series of high-speed CMOS logic devices. It shares functional similarities with the 74F240 and 74F241, differing primarily in input polarity and inversion characteristics. The 74F244 specifically provides non-inverting buffers with three-state outputs, suitable for bidirectional data flow management in digital circuits.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other 74F244 variants from different manufacturers offering identical pinouts and electrical specifications. Verify that any replacement maintains the same SOIC package dimensions and operating temperature range to ensure mechanical and environmental compatibility without circuit redesign.
