DC Characteristics
DC characteristics contain the spread of values guaranteed within the specified supply voltage and
temperature range unless otherwise specified. Typical characteristics represent the average value of
all parts.
Logic supply voltage: V_CC = 3.0 V ... 5.5 V, Junction temperature: T_J = -40°C … 140°C,
Bridge supply voltage : V_S = 7 V…34 V
(unless otherwise specified)
