Procurement Notes
Verify the specific package marking and manufacturer date code upon receipt to ensure authenticity. Confirm that the component matches the exact MC74LVX244DT designation, as suffixes may indicate different packaging or tape-and-reel configurations. Check datasheet revisions for any updates regarding electrical characteristics or recommended operating conditions before final integration.
Selection Notes
Select this component when designing systems requiring low-power consumption and compatibility between 3.3V/2.5V domains and 5V peripherals. The LVX series offers faster switching speeds compared to standard LVC variants while maintaining lower power dissipation. Ensure the application environment stays within the specified -40°C to 85°C temperature range for reliable performance.
Part Context
This part belongs to the MC74LVX244 family of octal buffers. It serves as a key interface solution in mixed-voltage digital circuits, bridging gaps between low-voltage processors and higher-voltage I/O devices. The device is widely used in portable electronics and industrial control systems where power efficiency and signal integrity are critical.
Replacement Considerations
Direct substitutes include SN74LV244APWR from Texas Instruments. Verify pinout compatibility and electrical specifications against the original datasheet before substitution.
