Gates And Inverters - Multi-Function, Configurable Procurement Notes

Verify the specific ordering suffix against the manufacturer's current guide, as variants such as LC3TR indicate tape-and-reel packaging while LC3 denotes cut tape. Confirm moisture sensitivity level (MSL3) requirements and maximum peak reflow temperature limits during assembly planning. Ensure the evaluation board documentation is consulted for proper grounding and impedance matching implementation.

Gates And Inverters - Multi-Function, Configurable Selection Notes

Select this component when designing circuits requiring fast XOR/XNOR logic at gigabit speeds. The integrated 50 Ω termination simplifies PCB layout by reducing the need for external resistors. Consider the programmable output swing feature if signal integrity optimization across varying trace lengths is required. Verify that the system power supply remains within the specified 3.0 V to 3.6 V range for optimal performance.
