ELECTRICAL CHARACTERISTICS
Definitions
All voltages are referenced to GND (pin 2). Positive currents flow into the IC. Sinking current means the current is flowing
into the pin; sourcing current means the current is flowing out of the pin.
Table 6. DC CHARACTERISTICS V_CC = 4.75 V to 5.25 V, T_J = −40°C to +150°C; R_LT = 60 W unless specified otherwise.
