Notes:
1. Excludes bias and modulation currents.
2. Bias and modulation currents add directly to power supply current in 5V applications. The additional supply current noted excludes these currents.
3. V_CC3 “supply OK” circuitry monitors the internally regulated 3.3V supply when V_CC = 5V (VCC3_SEL =low). When V_CC = 3.3V, V_CC3 “supply OK”
circuitry monitors V_CC (VCC3_SEL =high).
4. A low level at IBOUT_CA does not trigger a fault condition during common cathode operation.
5. A low level at IBOUT_CC does not trigger a fault condition during common anode operation.

AC Characteristics
(V_CC = 3.05 V to 3.55V or 4.7V to 5.5V, TA = -40 °C to +95 °C, unless otherwise noted)
Typical values for common anode are at V_CC = 3.3 V, IBOUTCA = 20 mA, IMOD = 20 mA, TA = 25 °C, unless otherwise noted.
Typical values for common cathode are at V_CC = 3.3 V, IBOUTCC = 5 mA, IMOD = 5 mA, TA = 25 °C, unless otherwise noted.
