range as specified. Notice that high modulation current means that the output voltage level is low.
The AC parameters are only specified in the range from -70 mA to -5 mA. However at T
ters are specified from -80 mA to -5 mA.
This is a leakage current. Max leakage current is present at max modulation current (i.e. at 70 mA modulation current).
The leakage current decreases for smaller leakage currents.
