12. HANDLING
Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is
desirable to take normal precautions appropriate to handling MOS devices.
13. DC CHARACTERISTICS
VDD1=1.8V to 3.3V, VSS=0V; Tamb = -30°C to +85°C; unless otherwise specified.
