W When using at Ta=25°C or higher 4.5mW to be reduced per 1°C. °C °C The Max value of Input Voltage/Output Voltage is not over 6.5V. When the pulse width is 50ns or less, the Min value of Input Voltage/Output Voltage is not under -1.0V. 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.
