• Unused inputs should be tied to V_DD or ground, never left floating
• Avoid exceeding maximum ratings to prevent latch-up or permanent damage
• For high-frequency applications, consider transmission line effects
• When driving capacitive loads, add series resistance to limit peak currents
• Observe proper ESD handling procedures during assembly and testing
