Even in the specified range of Power Supply Voltage, applying voltage only to the VCC side may cause an excessive current
to give a permanent damage to the IC.
When starting up power supplies, VEE and VCC should be powered on simultaneously or VEE first; then followed by VCC.
Reduced by 12 mW/℃ over 25℃, when installed on the standard board (size: 70x70x1.6mm).
