HANDLING
Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is
desirable to take normal handling precautions appropriate to handling MOS devices (see “Handling MOS Devices”).
CHARACTERISTICS
VDD = 2.4 to 6.0 V; VSS = 0 V; Tamb = −40 to +85 °C; (see Fig.3); unless otherwise specified.
