Input Voltage/ - -0.3 to Vcc+1.0 V When the pulse width is 50ns or less, the Min value of Input Output Voltage Voltage/Output Voltage is not below 1.0V. Junction Temperature Tjmax 150 C Junction temperature at the storage condition 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.
