L3234 - L3235
ELECTRICAL CHARACTERISTICS (Test conditions: V100 = +100V, VCC = +5V, Tamb = 25°C, unless oth-
erwise specified)
Note: Testing of all parameter is performed at 25°C. Characterisation, as well as the design rule used al-
low correlation of tested performance with actual performances at other temperatures. All pa-
rameters listed here are met in the range 0°C to +70°C. For applications requiring operations in
the standard temperature range (0°C to 70°C) use L3234. If operations are required in the ex-
tended temperature range (-40°C to 85°C), use the L3234T.
