Note 1: All I/O pins are clamped by internal diodes.
Note 2: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer
board. For detailed information on package thermal considerations, refer to www.maximintegrated.com/thermal-tutorial.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
Electrical Characteristics
(V_CC = +3.0V to +3.6V, C_CL = 75nF coupling capacitor on each output, R_L = 50I on each output, T_A = -40°C to +85°C, unless other-
wise noted. Typical values are at V_CC = +3.3V and T_A = +25°C.) (Note 3)
