*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)
