2. Derating: -3.5 mW/×C from 25° to 60°C.

This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must

be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, Vin

and Vout should be constrained to the range VSS £ (Vin or Vout) £ VDD except for the I/O, which can exceed VDD, and the Test input, which

can go below VSS.

Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs and/or an unused I/O

must be left open.

3. Pin soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may

cause malfunction or permanent damage to the device.

4. Freescale’s Package Reflow capability meets Pb-free requirements for JEDEC standerd J-STD-020C. For Peak Package Reflow
