(1) Current flow into device pins is defined as positive. Current flow out of device pins is defined as negative. All voltages are stated
referenced to V_EE = 0 V.
(2) Typical values are stated for V_CC = 3.3 V and T_A = 25°C.
(3) Recommended value — Parameter not tested.
(4) Recommended maximum capacitive load per bus segment is 400 pF.

(1) Typical values are stated for V_CC = 3.3 V and T_A = 25°C.
(2) Specification is ensured by characterization.
(3) Output return loss is dependent on board design. The LMH0303 meets this specification on the SD303EVK evaluation board.
