Description
74x Series Chip Arrays are single packaged devices containing an array of homogeneous resistor elements. Arrays
are typically used for convenience when several resistors occupy the same area in a layout. Multiple package
sizes and circuit configurations help save placement costs by reducing application component count.

Power Derating Curve – Typical
With the rated ambient temperature set to +70°C, the maximum power [maximum current for 0Ω product] at a temperature of no more
than rated ambient temperature shall be equal to the rated power [rate current for 0Ω product]. The maximum power at a temperature
exceeding the rated ambient temperature shall be a value determined by reducing the rated power according to the power reduction
curve in the figure below.
