74x Series Chip Resistor Arrays
The 74x Series Chip Arrays are single packaged devices containing an array of homogeneous resistor elements, designed for convenience when multiple resistors occupy the same area in a layout. They offer advantages such as low cost thick film technology, leadless surface mount construction, and improved TCR tracking compared to discrete resistors. These arrays reduce placement costs by minimizing component count and are available in various package sizes and circuit configurations.
