Electrical Specifications
Electrical characteristics are guaranteed over the full temperature range –20ºC <Tj< 105ºC. Ambient
temperature must be de-rated based upon power dissipation and package thermal characteristics.
Unless otherwise stated, test conditions are VCC = 5V, VDRIVE = 4.3V, V_IPROG = 0V.
