NOTES:
1. When V_CC = 5V, V_CC3 “supply OK” circuitry monitors the internally regulated 3.3V supply. When V_CC = 3.3V, V_CC3 “supply OK” circuitry monitors V_CC.

AC Characteristics
(V_CC = 3.05 V to 3.55V or 4.75V to 5.4V, T_A = -40 °C to +95 °C, unless otherwise noted)
Typical values are at V_CC = 3.3 V, I_BIASOUT = 30 mA, I_MOD = 30 mA, 25 ohm load and T_A = 25 °C, unless otherwise
noted.
