*Comments
Stresses above those listed under "Absolute Maximum
Ratings" may cause permanent damage to this device.
These are stress ratings only. Functional operation of this
device under these or any other conditions above those
indicated in the operational sections of this specification is
not implied or intended. Exposure to the absolute maximum
rating conditions for extended periods may affect device
reliability.

Note:
1. VDD = +5.0V, V0 = +30V, VI = VSS
2. VDD = +5.0V, V0 = +30V, fXCK = 20MHz, No-load, EI = VDD
The input data is turned over by the data taking clock (4-bit Parallel input mode)
3. VDD = +5.0V, V0 = +30V, fXCK = 20MHz, No-load. EI = VSS
The input data is turned over by the data taking clock (4-bit parallel input mode)
4. VDD = +5.0V, V0 = +30V, fXCK = 20MHz, fLP = 41.6kHz. fFR = 80 Hz, No-load
The input data is turned over by the data taking clock (4-bit parallel-input mode)
