10. 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 (see

“Handling MOS devices”).

11. DC CHARACTERISTICS

VDD = 2.6 V to 3.3V; VSS= 0 V; VLCD = 4.0 to 18.0V; Tamb = -30℃ to +85℃; unless otherwise specified.
