Procurement Notes

Verify the specific suffix against official documentation, as variations may exist between DTR2G and DTRG designations. Confirm RoHS compliance status and lead times directly with the manufacturer or authorized distributors prior to ordering. Ensure the selected package matches the PCB footprint requirements exactly.

Selection Notes

Select this component when designing systems requiring 16-bit wide data paths with low power consumption. The LCX series is appropriate for applications needing compatibility with both 3.3V and 2.5V logic levels. Consider the TSSOP-48 package constraints regarding thermal dissipation and board space availability during the layout phase.

Part Context

This part belongs to the MC74LCX16240 family of 16-bit buffers. It serves as a critical interface component in digital circuits, bridging different voltage domains while maintaining signal integrity. The LCX series is designed to offer performance comparable to older technologies while consuming significantly less power.

Replacement Considerations

Check for direct pin-compatible substitutes such as the MC74LCX16240DTR2G. Verify that any alternative maintains the same 16-bit configuration, three-state output capability, and compatible voltage specifications before implementation.
