Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure storage conditions adhere to specified humidity limits to prevent damage. Check for obsolescence notices as manufacturing statuses may change. Validate package markings against official datasheet specifications to avoid counterfeit parts.

Selection Notes

Select this component when designing systems requiring 16-bit data buffering with mixed voltage levels. It is suitable for applications needing 5V tolerance on both input and output sides while operating at lower core voltages. Consider the TSSOP-48 package constraints for PCB layout. Evaluate propagation delay requirements against system clock speeds to ensure timing compatibility.

Part Context

This part belongs to the 74LCX series of low-voltage CMOS logic devices. The LCX family is characterized by its ability to operate at reduced supply voltages while maintaining compatibility with standard 5V logic interfaces. Similar components in this category include other 16-bit buffers like the 74LVC162244, though voltage ranges and drive strengths may vary.

Replacement Considerations

Check for pin-compatible alternatives such as the 74LVC162244ADGG:11 from Nexperia, noting differences in operating temperature ranges and specific electrical characteristics. Verify that substitute parts maintain the required 5V tolerance and three-state functionality for direct replacement in existing designs.
