Input Voltage / - -0.3 to V +1.0 V When the pulse width is 50ns or less, the Min value of Input CC Output Voltage Voltage/Output Voltage is -1.0V. Junction Tjmax 150 C Junction temperature at the storage condition Temperature Electrostatic discharge voltage V -4000 to +4000 V ESD (human body model) Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings. (Note1) Not Recommended for New Designs.
