Procurement Notes

Verify the specific suffix 'AN' against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure the component meets RoHS requirements if applicable to your design constraints. Cross-reference the ordering information with onsemi documentation to validate availability and manufacturing status before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring octal buffering with three-state control. The HCT series ensures compatibility with standard TTL logic levels while offering CMOS power efficiency. Consider the 20-pin DIP package for through-hole mounting requirements and verify that the 5 V supply voltage aligns with your system's power distribution network.

Part Context

This part belongs to the 74HCT244 family of octal buffers and line drivers. It serves as a standard interface component for connecting microprocessors to memory or peripheral devices. The HCT variant specifically bridges the gap between older TTL standards and modern CMOS technologies, ensuring reliable signal integrity in mixed-logic environments.

Replacement Considerations

Check for direct equivalents such as MM74HCT244MTC or MC74HCT244ADTR2G-Q from onsemi. Verify pin compatibility and electrical specifications before substituting.
