**The thermal resistance from the semiconductor die to ambient is typically 120 C/W when the SO16 package is
mounted on a PCB in free air. The power dissipation of the device when loaded must be designed to keep the
device junction temperature below T
J MAX.
*During power-up and power-down, these voltage ratings require that signals be applied only when the power
supply is connected.
