Caution 1: 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.  
Caution 2: Should by any chance the maximum junction temperature rating be exceeded the rise in temperature of the chip may result in deterioration of the  
properties of the chip. In case of exceeding this absolute maximum rating, design a PCB with thermal resistance taken into consideration by  
increasing board size and copper area so as not to exceed the maximum junction temperature rating.  
(Note 1) The voltage that can be applied reference to GND (Pin 8, 18, 23).  
(Note 2) Do not exceed Tj=150°C.  
(Note 3) Refer to Recommended Operating Ratings for VDVDD  
.
(Note 4) This LSI should be used within AC peak limits at all conditions. Overshoot should be 30V with reference to GND.  
Undershoot should be 10ns and 30V with reference to VCCP1 and VCCP2. (Refer to Figure 3-1)  
(Note 5) This LSI should be used in lower than this rating by all means.  
Undershoot should be 10ns and (VOUT1P or VOUT1N or VOUT2P or VOUT2N) +7V. (Refer to Figure 3-2)
